Is there a way to create an alarm to be precise by a milisecond. Currently I used alarm(), together with the SIGALRM signal but that's too slow. I then tried with gettimeofday() but the cpu had overhead, using all 100%.
So is there a way to have something like ualarm() ?

Did you try? http://www.die.net/doc/linux/man/man3/ualarm.3.htmlSo is there a way to have something like ualarm() ?
If you understand what you're doing, you're not learning anything.

Depends on your definition of precise.
All desktop operating systems only specify minimum time for all delays of this kind because there is no way to be precise with all the different sources of interrupts, and the interactions of other tasks in the system.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
itsme86: thanx that should do.
