Can someone explain to me what the MIT SHM extensions are.
Just point me to the proper man pages would be enough, but
if you have the time a little more info wouldn't hurt.

Thanks,
Marc

This question belongs in comp.windows.x.

MIT-SHM is an extension to the X window system protocol which is
handled by the default configuration of the sample server from MIT
(and probably other vendors' servers, too). You can find out about
this by typing `xdpyinfo' to your X display:

...
number of extensions: 4

Multi-Buffering
MIT-SUNDRY-NONSTANDARD
...

The MIT-SHM extension provides a fast transfer method for pixmap data
for clients that run on the same machine as the server. I don't know
about any programs that use it, but SHM should be beneficial for
animation programs or so.
