Need C source documentation program

[Bob Ankeney]

     I'm looking for a C source code documentation program.  Something that,
for each function in a C program, lists the arguments passed, global variables
referenced/modified, and functions called.  Can anyone point me to such a beast?
Something that would embed the information as comments would be extra-nifty!

	Thanks,
	Bob Ankeney
