portability of a pause function

Hi everyone. I am using a pause function in a homework program and was wondering what the portability limitations would be (i.e. can it be used on other OS). The compiler I am using is MSVC++ v.6.0. and the function is

Code:

---

void pausing(int seconds)
{
  clock_t endtime = clock() + seconds * CLOCKS_PER_SEC;
  while ( ( clock() < endtime ) );
}

---

Thanks,

:)

That is actually a good example of portability. So yes.

Thank you for the replies.:D
The program I have coded is the classic tortoise vs. hare simulation, and the pause is being used to give the user the time to see the race as it is run. vVv, could you elaborate on your answer? I like to learn all of the nitty gritty of things.

Sincerely,
Eigenvalue
