Xorg return code

[Francis Giraldeau]

Hi,

I would like to know all the possible return code of Xorg. I didn't
found it in the doc, neither in the source code. I wonder where I can
find this information.

The point is that an older version of X was returning 0 when pressing
CTRL-ALT-Backspace, and now, it returns 134, and I would like to trap
the return code and act in consequence.

Thanks in advance,

Francis Giraldeau
