Inserting a delay ...

[kaftab]

I have the following code for inserting a delay in the program:

#include <time.h>
void CreateHPGL::sleep( clock_t wait )
{
   clock_t goal;
   goal = wait + clock();
   while( goal > clock() );
}

and I use it like this:

sleep(20000); // for a 20 second delay

It works fine on windows, however, on unix, there is no delay. Can someone point out the problem for me?
