xlib integrated debugging (Tracing)

Question

Hello

Is there any debugging options built-in in the Xlib (libX11.so)? Can I get list of X11 lib calls?

I want to get full trace of xlib function calls from heavy-multithreaded, closed-source program. It is one not-public embedded platform, so I can't use gdb for multithreaded debugging and there is no ltrace on the platform. Also, this program can't connect to x server over tcp/ip, only unix-socket. I want to do tracing of xlib calls from xlib itself.

Thanks!

ps. Xlib from rather modern xfree or even xorg. from gnu linux

You may be able to use xscope to monitor the requests sent over a Unix socket, even when you can't send the X protocol over TCP to be able to use network monitoring tools like Wireshark.
