The load routine returns a function pointer to the routine specified by
ld -e function.  There must be a way of getting the address of other functions
in the loaded object!?!.  Every other OS I've used with run time dynamic
libraries provides a find symbol routine.

There was an example posted here a while back using nlist.  That only works
if you know what the function symbol is for the "ld -e function" specified
was, not my case.

I've been looking at the loadquery( L_GETINFO,...) call.  I was hoping to make
use of the ld_info structure information, except that, I haven't been able
to figure it out.  First off I expected "ldinfo_next" to be zero as it said
in <sys/ldr.h> but it doesn't seem to be (is buffer and array of ld_info's?).
From there I tried looking down "ldinfo_textorg" at the xcoff struct but
really got lost there.  Any guiding light out there?

Thanks,
