Check out the ctags and cxref programs, available on most UNIX systems.

The easiest way might be to first compile the files and then
use nm(1) to obtain the symbols defined in each module.

Daniel Edelson                             ``Do you think we 
daniel@cis.ucsc.edu, or                      should test it before
...!sun!practic!peren!daniel                we ship it?''

Thanks for all the replies and postings to my question. Suggestions include
using sed, grep, ctags, nm, and cxref. I find that cxref(1) comes with SYS V
is exactly what I need and works very well. Anyone still using
sed/grep/ctags/nm should give cxref a look.

My only problem with cxref is rather Apollo specific. On Apollos, cxref is
under Sys 5.3 environment but all my programs are developed under BSD 4.3
environment. Worst yet, cxref is stamped as sys5.3 for systype and runtype so
even explicitly calling the program still put me into sys5.3 environment. The
result is cxref (actually /usr/lib/xcpp) couldn't find BSD style include
files, or complain about incorret system calling syntax. I did try using
-I/bsd4.3/usr/include but still no luck.

I wonder if anyone in Apollo land could give me some help?

There was a program posted a while back (as in server years ago) call 'id'
that does an excellent job of exactly what you want.  It was written by
Greg McGary.  At the bottom of a README file I found the following:

--             gmcgary@suneast.uu.net
--
--     After that, probably consulting in Europe...


so I am not sure what the current status of this program is.  This program
does have a copyright notice on it, so I don't just want to posted it
unless someone can convince me that I want get into any trouble :-).

Type at you later,
