Did they mean ctags?
Some development environments (IDE's) for Linux have that kind of thing. It's a pane with all of the functions listed.

www.freshmeat.net and search for C or C++ IDE. They work only under a given windowing environment, e.g. gnome, kde....

Also UltraEdit, which runs under Windows, will show a window that lists all of the functions in a given C file. You can download a demo version, and use it to look at the source file(s) you want to check.

www.ultredit.com

I think what those folks are talking about is nm. nm lists all of the symbols in a compiled C binary, if it has not been stripped. It also lists all of the external entry points, all of the global variables. I have never seen one that does this for C source.

They may also mean ctags - this creates an index file of functions. The somewhat human readable file is usually just called tags. Maybe you can use that. The first "column" is a list of functions, and you can write some perl or sed to extract the names.

shell

shell(1F)							   FMLI Commands							 shell(1F)

NAME

       shell - run a command using shell

SYNOPSIS

       shell command [command] ...

DESCRIPTION

       The  shell  function  concatenate  its arguments, separating each by a space, and passes this string to the shell ($SHELL if set, otherwise
       /usr/bin/sh).

EXAMPLES

       Example 1: A sample output of shell command.

       Since the Form and Menu Language does not directly support background processing, the shell function can be used instead.

       `shell "build prog > /dev/null &"`

       If you want the user to continue to be able to interact with the application while the background job is running, the  output  of  an  exe-
       cutable	run  by shell in the background must be redirected: to a file if you want to save the output, or to /dev/null if you don't want to
       save it (or if there is no output), otherwise your application may appear to be hung until the background job finishes processing.

       shell can also be used to execute a command that has the same name as an FMLI built-in function.

NOTES

       The arguments to shell will be concatenate using spaces, which may or may not do what is expected. The variables set in local  environments
       will not be expanded by the shell because "local" means "local to the current process."
