Description
Tool to analyze the control flow of C programs.
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).
The package also provides Emacs major mode for examining the produced flowcharts in Emacs.
