C function calling cross reference program needed

[Paul Lew]

I need a C function cross reference program which will generate listing
contains: list of function name + file name and all the function it calls,
e.g.,

file: /usr/tom/abc.c	contains:
	main ()
	{
		dd = xyz ();
		ee = zyx () + new (a, b);
	}

file: /usr/lib/lib1.c  contains:		file: /usr/lib/lib2.c  contains:
	xyz ()					zyx ()
	{					{
		....					....
	}					}

The output should be similar to the following:

	main	-- /usr/tom/abc.c

		xyz	-- /usr/lib/lib1.c
		zyx	-- /usr/lib/lib2.c
		new	-- 

	xyz	-- /usr/lib/lib1.c

		printf	--

	zyx	-- /usr/lib/lib2.c

		fopen	--
		fclose	--
		fgets	--

	Of course you have to specify the name of source files as input to
	this program in some way.  Is there something like this around?
	Please send mail directly.  Thanks!!
