function call flow tool for C

1. tceetree (http://sourceforge.net/p/tceetree/wiki/Home/) tceetree  could be useful for you when: you have the sources of an application written in C language; you would like to have a graphical representation of the entire or partial function call tree. If this is what you are looking for, follow these steps: Install (and compile)  CScope . A compiled Windows executable can be found  here . For a compiled Linux executable search the Web e.g. for a cscope RPM or Debian package. Install  Graphviz . Go to your sources root directory and do: under Windows:  dir /B /S *.c > cscope.files  (/B = bare format, no extra info); under Linux:  find . -name '*.c' > cscope.files ; that will recurse subdirectories and list all C files in  cscope.files . execute  cscope -b -c -R  (build the cross reference only, don't compress it, recurse); run tceetree with  cscope.out  as input (default) to get  tceetree.out...
