loop question for a time frame?

[metulburr]

Is there a way to make a loop execute for (let's say 5 seconds) and then break loop after the alotted time period is over?

[Turbine]

Remember to:
#include <time.h>

Code:

clock_t started = clock();

while(started - clock < 5000)
{
   //I suggest a sleep(1) here
}

"clock()" returns the system time at the moment it was called, in ms.

And is there any way to repeat an instruction on periods (for instance from 5 in 5 seconds)?
