SUMMARY: /usr/lib libraries contain ?

This answer was the most useful:

 Use the "nm" utility found in /usr/ccs/bin. For example

                /usr/ccs/bin/nm /usr/lib/libadm.a

        will spit out a list of symbols (functions, variables, etc)
        found in the library. Another method is just to look for
        the man page of the function. For example, doing

                man socket

        give me the man page which tells me I need the -lsocket
        and -lnsl libraries.

Also, someone suggested using "ar" which works on libraries that end with .a but
not those with .so.1

Other people suggested I set my LD_LIBRARY_PATH variable, but that wasn't the
problem, I just wasn't sure which libraries I should be using.

Thanks very much to all those who answered
