CGRAPH(1) General Commands Manual CGRAPH(1) NAME cgraph -- build call graphs from C files SYNOPSIS cgraph [-AcCGgPr] [-d num] [-i incl] [-R root] [file ...] DESCRIPTION The cgraph utility reads C source code files and prints call graphs from their contents. OPTIONS The following options are supported: -A Exclude ANSI C keywords. All globals and functions defined by the ANSI C standard are ignored. -c Print all calls within a function, including subsequent invoca- tions of the same function. -C Exclude C99 keywords. All globals and functions defined by the C99 standard are ignored. This does not include the ANSI C standard, but only new keywords of the C99 standard. -d num The depth at which the graph is cut off. The num argument must be a positive integer >=0. -G Exclude GCC specific keywords. All keywords defined and used by the GNU C compiler are ignored. -g Produce a dot(1) graph for graphviz output. -i incl Increase the number of included symbols. The incl argument can be one of the following characters: x Include external and static data symbols. _ Include names that begin with an underscore. -P Exclude POSIX keywords. All globals and functions defined by the IEEE Std 1003.1-2001 ("POSIX.1") specification are ignored. This does not include the ANSI C or C99 standards, but keywords of the IEEE Std 1003.1-2001 ("POSIX.1") specification. -r Print the flowgraph in reversed order, producing an inverted listing showing the callers of each function. -R root The function to use as root function. The default is "main". If set to a name, that cannot be found in the file, all functions are printed. EXAMPLES TODO EXIT STATUS The cgraph utility exits 0 on success, and >0 if an error occurs. SEE ALSO cflow(1), asmgraph(1) BUGS The cgraph utility does not process any macro substitution, preproces- sor conditions like #ifdef or #include directives, thus some calls within macros and function declarations within header files are not processed correctly. Use the cflow(1) utility if you want to have a better control over the flowgraph. AUTHORS Marcus von Appen <marcus@sysfault.org> FreeBSD ports 15.0 October 2, 2009 CGRAPH(1)
