Howto access command-stream?

[Clemens Eisserer]

Hello,

Is it possible to access Xlibs's command-stream-(buffer)?

I have a case where I have to use XLib because a large amount of code
is already using it and I don't want to rewrite it - however because
of performance reasons (the application is written in Java where
Java->C calls have some overhead) I would prefer if I could build my
commands myself and later inject it into Xlib.
I could allocate all resources through Xlib to avoid conflicts with
invalid resource IDs.

Any ideas wether this is possible at all?

Thank you in advance, lg Clemens
