Seems setitimer() can be used only one in a process.
and 1/1000 is not precise enough for a timer.
looking at linux real time implementation.
want to know the last news about the POSIX 1.b implement on
linux.
would you please give me some iformation?
since I can not find even at the last 2.4.0 kernel.
the kernel.org can only dl the souce code no much
information
gaven.
Thanks
