	Well, the answer (thank you Andy Vesper!) turned out to be
quite simple. I forgot that it was emailed to me, not posted to this
group. All you do is use the X function "XInitExtension()" . Give it
the display variable and the extension name, and it returns NULL
if the extension is not running.

if(XInitExtension (display,"X3D-PEX") == NULL)
{
   printf("\n Get a better machine, loser...\n");
   exit(0);
}


Thanks again Andy.
