[Question] - Linux vs Windows Xp

[Zxian]

For those of you who might be wondering about the test program, I e-mailed my prof and he sent me the source code:

#include <sys/types.h>
#include <sys/time.h>
#include <unistd.h>
#include <stdlib.h>
#include <stdio.h>

int main(int argc, char **argv)
{
	int i;
	time_t startTime = time(0), now;

	for (i = 0; i < 9; ++i) {
		if (!fork()) break;
	}

	i = 0;
	while (1) {
		++i;
		now = time(0);
		if (now - startTime > 60) break;
	}

	printf("%d counted to %d\n", getpid(), i); fflush(stdout);

	return 0;
}

As you can see, it's really simple, but an effective test for proper processor schduling.

It should complile in any Unix/Linux style OS, and in Windows, he compiled it under Cygwin.
