The answer is generally OS-specific, and you haven't revealed what
your target OS is.

On Linux with recent glibc versions, us dl_iterate_phdr().
On older Linux versions, and Solaris, use _r_debug.r_map.
HP-UX has shl_get_r()
AIX has loadquery(L_GETINFO, ...)

Other OSes probably have equivalent routines.
