test_noargs
Example program is called without arguments so that default range
[0..9] is used.
test_2_to_2000
Example program is called with "2" and "2000" as arguments.
test_overflow
Example program is called with "0" and "100000" as arguments. The
resulting sum is too large to be stored as an int variable.

/*
* example.c
*
* Calculate the sum of a given range of integer numbers. The range is
* specified by providing two integer numbers as command line argument.
* If no arguments are specified, assume the predefined range [0..9].
* Abort with an error message if the resulting number is too big to be
* stored as int variable.
*
* This program example is similar to the one found in the GCOV documentation.
* It is used to demonstrate the HTML output generated by LCOV.
*
* The program is split into 3 modules to better demonstrate the 'directory
* overview' function. There are also a lot of bloated comments inserted to
* artificially increase the source code size so that the 'source code
* overview' function makes at least a minimum of sense.

/*
* methods/gauss.c
*
* Calculate the sum of a given range of integer numbers.
*
* Somewhat of a more subtle way of calculation - and it even has a story
* behind it:
*
* Supposedly during math classes in elementary school, the teacher of
* young mathematician Gauss gave the class an assignment to calculate the
* sum of all natural numbers between 1 and 100, hoping that this task would
* keep the kids occupied for some time. The story goes that Gauss had the
* result ready after only a few minutes. What he had written on his black
* board was something like this:
*
* 1 + 100 = 101
* 2 + 99 = 101
* 3 + 98 = 101
* .
* .
* 100 + 1 = 101
*
* s = (1/2) * 100 * 101 = 5050
*
* A more general form of this formula would be
*
* s = (1/2) * (max + min) * (max - min + 1)
*
* which is used in the piece of code below to implement the requested
* function in constant time, i.e. without dependencies on the size of the
* input parameters.

.IR tracefile(s)
.RE
.SH DESCRIPTION
Create an HTML view of coverage data found in
.IR tracefile .
Note that
.I tracefile
may also be a list of filenames.
HTML output files are created in the current working directory unless the
\-\-output\-directory option is used. If
.I tracefile
ends with ".gz", it is assumed to be GZIP\-compressed and the gunzip tool
will be used to decompress it transparently.
Note that all source code files have to be present and readable at the
exact file system location they were compiled.
Use option
.I \--css\-file
to modify layout and colors of the generated HTML output. Files are
marked in different colors depending on the associated coverage rate. By
default, the coverage limits for low, medium and high coverage are set to
0\-75%, 75\-90% and 90\-100% percent respectively. To change these
values, use configuration file options
.IR genhtml_hi_limit " and " genhtml_med_limit .
Also note that when displaying percentages, 0% and 100% are only printed when
the values are exactly 0% and 100% respectively. Other values which would
conventionally be rounded to 0% or 100% are instead printed as nearest
non-boundary value. This behavior is in accordance with that of the
.BR gcov (1)
tool.
.SH OPTIONS
.B \-h
.br
.B \-\-help
.RS
Print a short help text, then exit.
.RE
.B \-v
.br
.B \-\-version
.RS
Print version number, then exit.
.RE
.B \-q
.br
.B \-\-quiet
.RS
Do not print progress messages.
Suppresses all informational progress output. When this switch is enabled,
only error or warning messages are printed.
.RE
.B \-f
.br
.B \-\-frames
.RS
Use HTML frames for source code view.
If enabled, a frameset is created for each source code file, providing
an overview of the source code as a "clickable" image. Note that this
option will slow down output creation noticeably because each source
code character has to be inspected once. Note also that the GD.pm Perl
module has to be installed for this option to work (it may be obtained
from http://www.cpan.org).
.RE
.B \-s
.br
.B \-\-show\-details
.RS
Generate detailed directory view.
When this option is enabled,
.B genhtml
generates two versions of each
file view. One containing the standard information plus a link to a
"detailed" version. The latter additionally contains information about
which test case covered how many lines of each source file.
.RE
.BI "\-b " baseline\-file
.br
.BI "\-\-baseline\-file " baseline\-file
.RS
Use data in
.I baseline\-file
as coverage baseline.
The tracefile specified by
.I baseline\-file
is read and all counts found in the original
.I tracefile
are decremented by the corresponding counts in
.I baseline\-file
before creating any output.
Note that when a count for a particular line in
.I baseline\-file
is greater than the count in the
.IR tracefile ,
the result is zero.
.RE
.BI "\-o " output\-directory
.br
.BI "\-\-output\-directory " output\-directory
.RS
Create files in
.I output\-directory.
Use this option to tell
.B genhtml
to write the resulting files to a directory other than
the current one. If
.I output\-directory
does not exist, it will be created.
It is advisable to use this option since depending on the
project size, a lot of files and subdirectories may be created.
.RE
.BI "\-t " title
.br
.BI "\-\-title " title
.RS
Display
.I title
in header of all pages.
.I title
is written to the header portion of each generated HTML page to
identify the context in which a particular output
was created. By default this is the name of the tracefile.
.RE
.BI "\-d " description\-file
.br
.BI "\-\-description\-file " description\-file
.RS
Read test case descriptions from
.IR description\-file .
All test case descriptions found in
.I description\-file
and referenced in the input data file are read and written to an extra page
which is then incorporated into the HTML output.
The file format of
.IR "description\-file " is:
for each test case:
.RS
TN:<testname>
.br
TD:<test description>
.RE
Valid test case names can consist of letters, numbers and the underscore
character ('_').
.RE
.B \-k
.br
.B \-\-keep\-descriptions
.RS
Do not remove unused test descriptions.
Keep descriptions found in the description file even if the coverage data
indicates that the associated test case did not cover any lines of code.
This option can also be configured permanently using the configuration file
option
.IR genhtml_keep_descriptions .
.RE
.BI "\-c " css\-file
.br
.BI "\-\-css\-file " css\-file
.RS
Use external style sheet file
.IR css\-file .
Using this option, an extra .css file may be specified which will replace
the default one. This may be helpful if the default colors make your eyes want
to jump out of their sockets :)
This option can also be configured permanently using the configuration file
option
.IR genhtml_css_file .
.RE
.BI "\-p " prefix
.br
.BI "\-\-prefix " prefix
.RS
Remove
.I prefix
from all directory names.
Because lists containing long filenames are difficult to read, there is a
mechanism implemented that will automatically try to shorten all directory
names on the overview page beginning with a common prefix. By default,
this is done using an algorithm that tries to find the prefix which, when
applied, will minimize the resulting sum of characters of all directory
names.
Use this option to specify the prefix to be removed by yourself.
.RE
.B \-\-no\-prefix
.RS
Do not remove prefix from directory names.
This switch will completely disable the prefix mechanism described in the
previous section.
This option can also be configured permanently using the configuration file
option
.IR genhtml_no_prefix .
.RE
.B \-\-no\-source
.RS
Do not create source code view.
Use this switch if you don't want to get a source code view for each file.
This option can also be configured permanently using the configuration file
option
.IR genhtml_no_source .
.RE
.BI "\-\-num\-spaces " spaces
.RS
Replace tabs in source view with
.I num
spaces.
Default value is 8.
This option can also be configured permanently using the configuration file
option
.IR genhtml_num_spaces .
.RE
.B \-\-highlight
.RS
Highlight lines with converted\-only coverage data.
Use this option in conjunction with the \-\-diff option of
.B lcov
to highlight those lines which were only covered in data sets which were
converted from previous source code versions.
This option can also be configured permanently using the configuration file
option
.IR genhtml_highlight .
.RE
.B \-\-legend
.RS
Include color legend in HTML output.
Use this option to include a legend explaining the meaning of color coding
in the resulting HTML output.
This option can also be configured permanently using the configuration file
option
.IR genhtml_legend .
.RE
.BI "\-\-html\-prolog " prolog\-file
.RS
Read customized HTML prolog from
.IR prolog\-file .
Use this option to replace the default HTML prolog (the initial part of the
HTML source code leading up to and including the <body> tag) with the contents
of
.IR prolog\-file .
Within the prolog text, the following words will be replaced when a page is generated:
.B "@pagetitle@"
.br
The title of the page.
.B "@basedir@"
.br
A relative path leading to the base directory (e.g. for locating css\-files).
This option can also be configured permanently using the configuration file
option
.IR genhtml_html_prolog .
.RE
.BI "\-\-html\-epilog " epilog\-file
.RS
Read customized HTML epilog from
.IR epilog\-file .
Use this option to replace the default HTML epilog (the final part of the HTML
source including </body>) with the contents of
.IR epilog\-file .
Within the epilog text, the following words will be replaced when a page is generated:
.B "@basedir@"
.br
A relative path leading to the base directory (e.g. for locating css\-files).
This option can also be configured permanently using the configuration file
option
.IR genhtml_html_epilog .
.RE
.BI "\-\-html\-extension " extension
.RS
Use customized filename extension for generated HTML pages.
This option is useful in situations where different filename extensions
are required to render the resulting pages correctly (e.g. php). Note that
a '.' will be inserted between the filename and the extension specified by
this option.
This option can also be configured permanently using the configuration file
option
.IR genhtml_html_extension .
.RE
.B \-\-html\-gzip
.RS
Compress all generated html files with gzip and add a .htaccess file specifying
gzip\-encoding in the root output directory.
Use this option if you want to save space on your webserver. Requires a
webserver with .htaccess support and a browser with support for gzip
compressed html.
This option can also be configured permanently using the configuration file
option
.IR genhtml_html_gzip .
.RE
.B \-\-sort
.br
.B \-\-no\-sort
.RS
Specify whether to include sorted views of file and directory overviews.
Use \-\-sort to include sorted views or \-\-no\-sort to not include them.
Sorted views are
.B enabled
by default.
When sorted views are enabled, each overview page will contain links to
views of that page sorted by coverage rate.
This option can also be configured permanently using the configuration file
option
.IR genhtml_sort .
.RE
.B \-\-function\-coverage
.br
.B \-\-no\-function\-coverage
.RS
Specify whether to display function coverage summaries in HTML output.
Use \-\-function\-coverage to enable function coverage summaries or
\-\-no\-function\-coverage to disable it. Function coverage summaries are
.B enabled
by default
When function coverage summaries are enabled, each overview page will contain
the number of functions found and hit per file or directory, together with
the resulting coverage rate. In addition, each source code view will contain
a link to a page which lists all functions found in that file plus the
respective call count for those functions.
This option can also be configured permanently using the configuration file
option
.IR genhtml_function_coverage .
.RE
.B \-\-branch\-coverage
.br
.B \-\-no\-branch\-coverage
.RS
Specify whether to display branch coverage data in HTML output.
Use \-\-branch\-coverage to enable branch coverage display or
\-\-no\-branch\-coverage to disable it. Branch coverage data display is
.B enabled
by default
When branch coverage display is enabled, each overview page will contain
the number of branches found and hit per file or directory, together with
the resulting coverage rate. In addition, each source code view will contain
an extra column which lists all branches of a line with indications of
whether the branch was taken or not. Branches are shown in the following format:
' + ': Branch was taken at least once
.br
' - ': Branch was not taken
.br
' # ': The basic block containing the branch was never executed
.br
Note that it might not always be possible to relate branches to the
corresponding source code statements: during compilation, GCC might shuffle
branches around or eliminate some of them to generate better code.
This option can also be configured permanently using the configuration file
option
.IR genhtml_branch_coverage .
.RE
.B \-\-demangle\-cpp
.RS
Specify whether to demangle C++ function names.
Use this option if you want to convert C++ internal function names to
human readable format for display on the HTML function overview page.
This option requires that the c++filt tool is installed (see
.BR c++filt (1)).
.RE
.B \-\-ignore\-errors
.I errors
.br

.SH DESCRIPTION
.B geninfo
converts all GCOV coverage data files found in
.I directory
into tracefiles, which the
.B genhtml
tool can convert to HTML output.
Unless the \-\-output\-filename option is specified,
.B geninfo
writes its
output to one file per .da file, the name of which is generated by simply
appending ".info" to the respective .da file name.
Note that the current user needs write access to both
.I directory
as well as to the original source code location. This is necessary because
some temporary files have to be created there during the conversion process.
Note also that
.B geninfo
is called from within
.BR lcov ,
so that there is usually no need to call it directly.
.B Exclusion markers
To exclude specific lines of code from a tracefile, you can add exclusion
markers to the source code. Additionally you can exclude specific branches from
branch coverage without excluding the involved lines from line and function
coverage. Exclusion markers are keywords which can for example be added in the
form of a comment.
See
.BR lcovrc (5)
how to override some of them.
The following markers are recognized by geninfo:
LCOV_EXCL_LINE
.RS
Lines containing this marker will be excluded.
.br
.RE
LCOV_EXCL_START
.RS
Marks the beginning of an excluded section. The current line is part of this

.SH OPTIONS
.B \-b
.I directory
.br
.B \-\-base\-directory
.I directory
.br
.RS
.RI "Use " directory
as base directory for relative paths.
Use this option to specify the base directory of a build\-environment
when geninfo produces error messages like:
.RS
ERROR: could not read source file /home/user/project/subdir1/subdir2/subdir1/subdir2/file.c
.RE
In this example, use /home/user/project as base directory.
This option is required when using geninfo on projects built with libtool or
similar build environments that work with a base directory, i.e. environments,
where the current working directory when invoking the compiler is not the same
directory in which the source code file is located.
Note that this option will not work in environments where multiple base
directories are used. In that case use configuration file setting
.B geninfo_auto_base=1
(see
.BR lcovrc (5)).
.RE
.B \-\-checksum
.br
.B \-\-no\-checksum
.br
.RS
Specify whether to generate checksum data when writing tracefiles.
Use \-\-checksum to enable checksum generation or \-\-no\-checksum to
disable it. Checksum generation is
.B disabled
by default.
When checksum generation is enabled, a checksum will be generated for each
source code line and stored along with the coverage data. This checksum will
be used to prevent attempts to combine coverage data from different source
code versions.
If you don't work with different source code versions, disable this option
to speed up coverage data processing and to reduce the size of tracefiles.
.RE
.B \-\-compat
.IR mode = value [, mode = value ,...]
.br
.RS
Set compatibility mode.
Use \-\-compat to specify that geninfo should enable one or more compatibility
modes when capturing coverage data. You can provide a comma-separated list
of mode=value pairs to specify the values for multiple modes.
Valid
.I values
are:
.B on
.RS
Enable compatibility mode.
.RE
.B off
.RS
Disable compatibility mode.
.RE
.B auto
.RS
Apply auto-detection to determine if compatibility mode is required. Note that
auto-detection is not available for all compatibility modes.
.RE
If no value is specified, 'on' is assumed as default value.
Valid
.I modes
are:
.B libtool
.RS
Enable this mode if you are capturing coverage data for a project that
was built using the libtool mechanism. See also
\-\-compat\-libtool.
The default value for this setting is 'on'.
.RE
.B hammer
.RS
Enable this mode if you are capturing coverage data for a project that
was built using a version of GCC 3.3 that contains a modification
(hammer patch) of later GCC versions. You can identify a modified GCC 3.3
by checking the build directory of your project for files ending in the
extension '.bbg'. Unmodified versions of GCC 3.3 name these files '.bb'.
The default value for this setting is 'auto'.
.RE
.B split_crc
.RS
Enable this mode if you are capturing coverage data for a project that
was built using a version of GCC 4.6 that contains a modification
(split function checksums) of later GCC versions. Typical error messages
when running geninfo on coverage data produced by such GCC versions are
\'out of memory' and 'reached unexpected end of file'.
The default value for this setting is 'auto'
.RE
.RE
.B \-\-compat\-libtool
.br
.B \-\-no\-compat\-libtool
.br
.RS
Specify whether to enable libtool compatibility mode.
Use \-\-compat\-libtool to enable libtool compatibility mode or \-\-no\-compat\-libtool
to disable it. The libtool compatibility mode is
.B enabled
by default.
When libtool compatibility mode is enabled, geninfo will assume that the source
code relating to a .da file located in a directory named ".libs" can be
found in its parent directory.
If you have directories named ".libs" in your build environment but don't use
libtool, disable this option to prevent problems when capturing coverage data.
.RE
.B \-\-config\-file
.I config\-file
.br
.RS
Specify a configuration file to use.
When this option is specified, neither the system\-wide configuration file
/etc/lcovrc, nor the per\-user configuration file ~/.lcovrc is read.
This option may be useful when there is a need to run several
instances of
.B geninfo
with different configuration file options in parallel.
.RE
.B \-\-derive\-func\-data
.br
.RS
Calculate function coverage data from line coverage data.
Use this option to collect function coverage data, even if the version of the
gcov tool installed on the test system does not provide this data. lcov will
instead derive function coverage data from line coverage data and
information about which lines belong to a function.
.RE
.B \-\-exclude
.I pattern
.br
.RS
Exclude source files matching
.IR pattern .
Use this switch if you want to exclude coverage data for a particular set
of source files matching any of the given patterns. Multiple patterns can be
specified by using multiple
.B --exclude
command line switches. The
.I patterns
will be interpreted as shell wildcard patterns (note that they may need to be
escaped accordingly to prevent the shell from expanding them first).
Can be combined with the
.B --include
command line switch. If a given file matches both the include pattern and the
exclude pattern, the exclude pattern will take precedence.
.RE
.B \-\-external
.br
.B \-\-no\-external
.br
.RS
Specify whether to capture coverage data for external source files.
External source files are files which are not located in one of the directories
specified by \-\-directory or \-\-base\-directory. Use \-\-external to include
external source files while capturing coverage data or \-\-no\-external to
ignore this data.
Data for external source files is
.B included
by default.

will be interpreted as shell wildcard patterns (note that they may need to be
escaped accordingly to prevent the shell from expanding them first).
.RE
.B \-\-ignore\-errors
.I errors
.br
.RS

Use this option to specify a list of one or more classes of errors after which
geninfo should continue processing instead of aborting.
.I errors
can be a comma\-separated list of the following keywords:
.B gcov:
the gcov tool returned with a non\-zero return code.
.B source:
the source code file for a data set could not be found.
.RE
.B \-i
.br
.B \-\-initial
.RS
Capture initial zero coverage data.
Run geninfo with this option on the directories containing .bb, .bbg or .gcno
files before running any test case. The result is a "baseline" coverage data
file that contains zero coverage for every instrumented line and function.
Combine this data file (using lcov \-a) with coverage data files captured
after a test run to ensure that the percentage of total lines covered is
correct even when not all object code files were loaded during the test.
Note: currently, the \-\-initial option does not generate branch coverage
information.

Following is a quick description of the tracefile format as used by
.BR genhtml ", " geninfo " and " lcov .
A tracefile is made up of several human\-readable lines of text,
divided into sections. If available, a tracefile begins with the
.I testname
which is stored in the following format:
TN:<test name>
For each source file referenced in the .da file, there is a section containing
filename and coverage data:
SF:<absolute path to the source file>
Following is a list of line numbers for each function name found in the
source file:
FN:<line number of function start>,<function name>
Next, there is a list of execution counts for each instrumented function:
FNDA:<execution count>,<function name>
This list is followed by two lines containing the number of functions found
and hit:
FNF:<number of functions found>
FNH:<number of function hit>
Branch coverage information is stored which one line per branch:
BRDA:<line number>,<block number>,<branch number>,<taken>
Block number and branch number are gcc internal IDs for the branch. Taken is
either '-' if the basic block containing the branch was never executed or
a number indicating how often that branch was taken.
Branch coverage summaries are stored in two lines:
BRF:<number of branches found>
BRH:<number of branches hit>
Then there is a list of execution counts for each instrumented line
(i.e. a line which resulted in executable code):
DA:<line number>,<execution count>[,<checksum>]
Note that there may be an optional checksum present for each instrumented
line. The current
.B geninfo
implementation uses an MD5 hash as checksumming algorithm.
At the end of a section, there is a summary about how many lines
were found and how many were actually instrumented:
LH:<number of lines with a non\-zero execution count>
LF:<number of instrumented lines>
Each sections ends with:
end_of_record
In addition to the main source code file there are sections for all
#included files which also contain executable code.
Note that the absolute path of a source file is generated by interpreting
the contents of the respective .bb file (see
.BR "gcov " (1)
for more information on this file type). Relative filenames are prefixed
with the directory in which the .bb file is found.
Note also that symbolic links to the .bb file will be resolved so that the
actual file path is used instead of the path to a link. This approach is
necessary for the mechanism to work with the /proc/gcov files.

.SH DESCRIPTION
.B lcov
is a graphical front\-end for GCC's coverage testing tool gcov. It collects
line, function and branch coverage data for multiple source files and creates
HTML pages containing the source code annotated with coverage information.
It also adds overview pages for easy navigation within the file structure.
Use
.B lcov
to collect coverage data and
.B genhtml
to create HTML pages. Coverage data can either be collected from the
currently running Linux kernel or from a user space application. To do this,
you have to complete the following preparation steps:
For Linux kernel coverage:
.RS
Follow the setup instructions for the gcov\-kernel infrastructure:
.I http://ltp.sourceforge.net/coverage/gcov.php
.br
.RE
For user space application coverage:
.RS
Compile the application with GCC using the options
"\-fprofile\-arcs" and "\-ftest\-coverage".
.RE
Please note that this man page refers to the output format of
.B lcov
as ".info file" or "tracefile" and that the output of GCOV
is called ".da file".
Also note that when printing percentages, 0% and 100% are only printed when
the values are exactly 0% and 100% respectively. Other values which would
conventionally be rounded to 0% or 100% are instead printed as nearest
non-boundary value. This behavior is in accordance with that of the
.BR gcov (1)
tool.

.B \-\-capture
.br
.RS
Capture coverage data.
By default captures the current kernel execution counts and writes the
resulting coverage data to the standard output. Use the \-\-directory
option to capture counts for a user space program.
The result of the capture operation will be written to stdout or the tracefile
specified with \-o.
Only one of \-z, \-c, \-a, \-e, \-r, \-l, \-\-diff or \-\-summary may be
specified at a time.
.RE
.B \-\-checksum
.br
.B \-\-no\-checksum
.br
.RS
Specify whether to generate checksum data when writing tracefiles.
Use \-\-checksum to enable checksum generation or \-\-no\-checksum to
disable it. Checksum generation is
.B disabled
by default.
When checksum generation is enabled, a checksum will be generated for each
source code line and stored along with the coverage data. This checksum will
be used to prevent attempts to combine coverage data from different source
code versions.
If you don't work with different source code versions, disable this option
to speed up coverage data processing and to reduce the size of tracefiles.
.RE
.B \-\-compat
.IR mode = value [, mode = value ,...]
.br
.RS
Set compatibility mode.
Use \-\-compat to specify that lcov should enable one or more compatibility
modes when capturing coverage data. You can provide a comma-separated list
of mode=value pairs to specify the values for multiple modes.
Valid
.I values
are:
.B on
.RS
Enable compatibility mode.
.RE
.B off
.RS
Disable compatibility mode.
.RE
.B auto
.RS
Apply auto-detection to determine if compatibility mode is required. Note that
auto-detection is not available for all compatibility modes.
.RE
If no value is specified, 'on' is assumed as default value.
Valid
.I modes
are:
.B libtool
.RS
Enable this mode if you are capturing coverage data for a project that
was built using the libtool mechanism. See also
\-\-compat\-libtool.
The default value for this setting is 'on'.
.RE
.B hammer
.RS
Enable this mode if you are capturing coverage data for a project that
was built using a version of GCC 3.3 that contains a modification
(hammer patch) of later GCC versions. You can identify a modified GCC 3.3
by checking the build directory of your project for files ending in the
extension '.bbg'. Unmodified versions of GCC 3.3 name these files '.bb'.
The default value for this setting is 'auto'.
.RE
.B split_crc
.RS
Enable this mode if you are capturing coverage data for a project that
was built using a version of GCC 4.6 that contains a modification
(split function checksums) of later GCC versions. Typical error messages
when running lcov on coverage data produced by such GCC versions are
\'out of memory' and 'reached unexpected end of file'.
The default value for this setting is 'auto'
.RE
.RE
.B \-\-compat\-libtool
.br
.B \-\-no\-compat\-libtool
.br
.RS
Specify whether to enable libtool compatibility mode.
Use \-\-compat\-libtool to enable libtool compatibility mode or \-\-no\-compat\-libtool
to disable it. The libtool compatibility mode is
.B enabled
by default.
When libtool compatibility mode is enabled, lcov will assume that the source
code relating to a .da file located in a directory named ".libs" can be
found in its parent directory.
If you have directories named ".libs" in your build environment but don't use
libtool, disable this option to prevent problems when capturing coverage data.
.RE
.B \-\-config\-file
.I config\-file
.br
.RS
Specify a configuration file to use.
When this option is specified, neither the system\-wide configuration file
/etc/lcovrc, nor the per\-user configuration file ~/.lcovrc is read.
This option may be useful when there is a need to run several
instances of
.B lcov
with different configuration file options in parallel.
.RE
.B \-\-convert\-filenames

Convert filenames when applying diff.
Use this option together with \-\-diff to rename the file names of processed
data sets according to the data provided by the diff.
.RE
.B \-\-diff
.I tracefile
.I difffile
.br
.RS
Convert coverage data in
.I tracefile
using source code diff file
.IR difffile .
Use this option if you want to merge coverage data from different source code
levels of a program, e.g. when you have data taken from an older version
and want to combine it with data from a more current version.
.B lcov
will try to map source code lines between those versions and adjust the coverage
data respectively.
.I difffile
needs to be in unified format, i.e. it has to be created using the "\-u" option
of the
.B diff
tool.
Note that lines which are not present in the old version will not be counted
as instrumented, therefore tracefiles resulting from this operation should
not be interpreted individually but together with other tracefiles taken
from the newer version. Also keep in mind that converted coverage data should
only be used for overview purposes as the process itself introduces a loss
of accuracy.
The result of the diff operation will be written to stdout or the tracefile
specified with \-o.
Only one of \-z, \-c, \-a, \-e, \-r, \-l, \-\-diff or \-\-summary may be
specified at a time.
.RE

.RS
Use .da files in
.I directory
instead of kernel.
If you want to work on coverage data for a user space program, use this
option to specify the location where the program was compiled (that's
where the counter files ending with .da will be stored).
Note that you may specify this option more than once.
.RE
.B \-\-exclude
.I pattern
.br
.RS
Exclude source files matching
.IR pattern .
Use this switch if you want to exclude coverage data for a particular set
of source files matching any of the given patterns. Multiple patterns can be
specified by using multiple
.B --exclude
command line switches. The
.I patterns
will be interpreted as shell wildcard patterns (note that they may need to be
escaped accordingly to prevent the shell from expanding them first).
Can be combined with the
.B --include
command line switch. If a given file matches both the include pattern and the
exclude pattern, the exclude pattern will take precedence.
.RE
.B \-\-external

External source files are files which are not located in one of the directories
specified by \-\-directory or \-\-base\-directory. Use \-\-external to include
external source files while capturing coverage data or \-\-no\-external to
ignore this data.
Data for external source files is

which matches at least one of those patterns will be extracted.
The result of the extract operation will be written to stdout or the tracefile

.B \-\-initial
.RS
Capture initial zero coverage data.
Run lcov with \-c and this option on the directories containing .bb, .bbg
or .gcno files before running any test case. The result is a "baseline"
coverage data file that contains zero coverage for every instrumented line.
Combine this data file (using lcov \-a) with coverage data files captured
after a test run to ensure that the percentage of total lines covered is
correct even when not all source code files were loaded during the test.
Recommended procedure when capturing data for a test case:
1. create baseline coverage data file

lcovrc \- lcov configuration file
.SH DESCRIPTION
The
.I lcovrc
file contains configuration information for the
.B lcov
code coverage tool (see
.BR lcov (1)).
.br
The system\-wide configuration file is located at
.IR /etc/lcovrc .
To change settings for a single user, place a customized copy of this file at
location
.IR ~/.lcovrc .
Where available, command\-line options override configuration file settings.
Lines in a configuration file can either be:
.IP " *"
empty lines or lines consisting only of white space characters. These lines are
ignored.
.IP " *"
comment lines which start with a hash sign ('#'). These are treated like empty
lines and will be ignored.
.IP " *"
statements in the form
.RI ' key " = " value '.
A list of valid statements and their description can be found in
section 'OPTIONS' below.

.PP
.BR genhtml_charset " ="
.I charset
.IP
Specify the character set of all generated HTML pages.
.br
Use this option if the source code contains characters which are not
part of the default character set. Note that this option is ignored
when a custom HTML prolog is specified (see also
.BR genhtml_html_prolog ).
.br
Default is UTF-8.
.PP
.BR genhtml_demangle_cpp " ="
.IR 0 | 1
.IP
If non-zero, demangle C++ function names in function overviews.
Set this option to one if you want to convert C++ internal function
names to human readable format for display on the HTML function overview
page. This option requires that the c++filt tool is installed (see
.BR c++filt(1)
).
.br
This option corresponds to the \-\-demangle\-cpp command line option of
.BR genhtml .
.br
Default is 0.
.PP
.BR genhtml_desc_html " ="
.IR 0 | 1
.IP
If non-zero, test case descriptions may contain HTML markup.
Set this option to one if you want to embed HTML markup (for example to
include links) in test case descriptions. When set to zero, HTML markup
characters will be escaped to show up as plain text on the test case
description page.
.br
Default is 0.
.PP
.BR genhtml_precision " ="
.IR 1 | 2 | 3 | 4
.IP
Specify how many digits after the decimal-point should be used for
displaying coverage rates.
.br
Default is 1.

.IP
If non\-zero, adjust test names to include operating system information
when capturing coverage data.
.br
Default is 0.
.PP
.BR geninfo_checksum " ="
.IR 0 | 1
.IP
If non\-zero, generate source code checksums when capturing coverage data.
Checksums are useful to prevent merging coverage data from incompatible
source code versions but checksum generation increases the size of coverage
files and the time used to generate those files.
.br
This option corresponds to the \-\-checksum and \-\-no\-checksum command line
option of
.BR geninfo .
.br
Default is 0.
.PP
.BR geninfo_compat_libtool " ="
.IR 0 | 1
.IP
If non\-zero, enable libtool compatibility mode. When libtool compatibility
mode is enabled, lcov will assume that the source code relating to a .da file
located in a directory named ".libs" can be found in its parent directory.
.br
This option corresponds to the \-\-compat\-libtool and \-\-no\-compat\-libtool
command line option of
.BR geninfo .
.br
Default is 1.
.PP
.BR geninfo_external " ="
.IR 0 | 1
.IP
If non\-zero, capture coverage data for external source files.
External source files are files which are not located in one of the directories
(including sub-directories)
specified by the \-\-directory or \-\-base\-directory options of
.BR lcov / geninfo .
Default is 1.
.PP
.BR geninfo_gcov_all_blocks " ="
.IR 0 | 1
.IP
If non\-zero, call the gcov tool with option --all-blocks.
Using --all-blocks will produce more detailed branch coverage information for
each line. Set this option to zero if you do not need detailed branch coverage
information to speed up the process of capturing code coverage or to work
around a bug in some versions of gcov which will cause it to endlessly loop
when analysing some files.
Default is 1.
.PP
.BR geninfo_compat " ="
.IR mode = value [, mode = value ,...]
.IP
Specify that geninfo should enable one or more compatibility modes
when capturing coverage data.
This option corresponds to the \-\-compat command line option of
.BR geninfo .
Default is 'libtool=on, hammer=auto, split_crc=auto'.
.PP
.BR geninfo_adjust_src_path " ="
.IR pattern " => " replacement
.br
.BR geninfo_adjust_src_path " ="
.I pattern
.IP
Adjust source paths when capturing coverage data.
Use this option in situations where geninfo cannot find the correct
path to source code files of a project. By providing a
.I pattern
in Perl regular expression format (see
.BR perlre (1))
and an optional replacement string, you can instruct geninfo to
remove or change parts of the incorrect source path.
.B Example:
.br
1. When geninfo reports that it cannot find source file
.br
/path/to/src/.libs/file.c
.br
while the file is actually located in
.br
/path/to/src/file.c
.br
use the following parameter:
.br
geninfo_adjust_src_path = /.libs
This will remove all "/.libs" strings from the path.
2. When geninfo reports that it cannot find source file
.br
/tmp/build/file.c
.br
while the file is actually located in
.br
/usr/src/file.c
.br
use the following parameter:
.br
geninfo_adjust_src_path = /tmp/build => /usr/src
.br
This will change all "/tmp/build" strings in the path to "/usr/src".
.PP
.BR geninfo_auto_base " ="
.IR 0 | 1
.IP
If non\-zero, apply a heuristic to determine the base directory when
collecting coverage data.
.br
Use this option when using geninfo on projects built with libtool or
similar build environments that work with multiple base directories,
i.e. environments, where the current working directory when invoking the
compiler ist not the same directory in which the source code file is
located, and in addition, is different between files of the same project.
.br
Default is 1.
.PP
.BR lcov_gcov_dir " ="
.I path_to_kernel_coverage_data
.IP
Specify the path to the directory where kernel coverage data can be found
or leave undefined for auto-detection.
.br
Default is auto-detection.
.PP
.BR lcov_tmp_dir " ="
.I temp
.IP
Specify the location of a directory used for temporary files.
.br
Default is '/tmp'.
.PP
.BR lcov_list_full_path " ="
.IR 0 | 1
.IP
If non-zero, print the full path to source code files during a list operation.
.br
This option corresponds to the \-\-list\-full\-path option of
.BR lcov .
.br
Default is 0.
.PP
.BR lcov_list_max_width " ="
.IR width
.IP
Specify the maximum width for list output. This value is ignored when
lcov_list_full_path is non\-zero.
.br
Default is 80.
.PP
.BR lcov_list_truncate_max
.B " ="
.IR percentage
.IP
Specify the maximum percentage of file names which may be truncated when
choosing a directory prefix in list output. This value is ignored when
lcov_list_full_path is non\-zero.
.br
Default is 20.
.PP
.BR lcov_function_coverage " ="
.IR 0 | 1
.IP
Specify whether lcov should handle function coverage data.
.br
Setting this option to 0 can reduce memory and CPU time consumption
when lcov is collecting and processing coverage data, as well as
reduce the size of the resulting data files. Note that setting
.B genhtml_function_coverage
will override this option for HTML generation.
.br
Default is 1.
.PP
.BR lcov_branch_coverage " ="
.IR 0 | 1
.IP
Specify whether lcov should handle branch coverage data.
.br
Setting this option to 0 can reduce memory and CPU time consumption
when lcov is collecting and processing coverage data, as well as
reduce the size of the resulting data files. Note that setting
.B genhtml_branch_coverage
will override this option for HTML generation.
.br
Default is 0.
.PP
.BR lcov_excl_line " ="
