Within the program itself:

man dladdr

Outside the program itself:

man atos

The debugger, gdb, also has multiple modes in which it operates, two of which can be programmatically controlled (to permit things like GUIs that still use gdb internally). You could open the binary with gdb in one of these modes and interactively query gdb for the information.

Can you tell me what these modes are? Or at least what to look for in the manual?

The GDB/MI Interface

Thank you, I'll spend some time reading through it all.

My first choice is GDB, if I can get it to launch GUI apps correctly. However, for alpha/beta testing, the dladdr trick is probably what I'll need. Crash reports just don't give enough info on how I got into the state I'm currently in.

You can attach GUI apps after they are already launched.

My crash happens before the run loop starts, so I don't have time to attach... :-/ Oh well, I guess its back to using sleep() for a long while in main, and trying to attach before I get out of sleep. Thanks for the help! Thanks, Cem Karan _______________________________________________ Do not post admin requests to the list. They will be ignored.
