prolly not. because there are two ways to handle the mouse under linux:
using gpm (on the console) and handling it as an XEvent when running under
X. the latter is more portable (works will all UNIX'es). don't know zip
about gpm.

this is easy. you use this function called setitimer() and register a
signal handler. at the countdown interval (which you set, under linux the
resolution is 10ms, unless you're using RTlinux), the signal handler gets
called. afaik i think this also works under djgpp.
