CFLOW(1) | cflow manual | CFLOW(1) |
NAME¶
cflow - analyze control flow in C source files
SYNOPSIS¶
cflow [option...] file...
cflow {--help | --usage | --version | -V}
DESCRIPTION¶
This manual page documents briefly the cflow command.
This manual page was written for the Debian distribution because the original program does not have a manual page. Instead, it has documentation in the GNU info(1) format.
GNU cflow analyzes a collection of C source files and prints a graph, charting control flow within the program.
GNU cflow is able to produce both direct and inverted flowgraphs for C sources. Optionally a cross-reference listing can be generated. Two output formats are implemented: POSIX and GNU (extended).
Input files can optionally be preprocessed before analyzing.
OPTIONS¶
A summary of options is included below. For a complete description, see the info(1) files.
The program follows the usual GNU command line syntax, with long options starting with two dashes (-). Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options.
The effect of each option marked with an asterisk is reversed if the option's long name is prefixed with ‘no-’. For example, ‘--no-cpp’ cancels ‘--cpp’.
