sleep() bug part 2?

hi

still trying to figure out why sleep hangs in the program I am porting.  I
wrote a simple test program to try to mimic the problems that the program I
am working on is giving me and that also gives me weird results (I assure
you it's extremely short).


#include <stdio.h>
#include <unistd.h>
#include <pthread.h>

#define SLEEP 2
#define MILLION 1000000


void *thread_func1 (void *arg){

	printf ("are we in thread 1?\n");

	while (1){
		sleep (SLEEP);
		printf ("1:  after %d second sleep\n", SLEEP1);
	}
}

void *thread_func2(void *arg){

	printf ("are we in thread 2?\n");
	long c = 0;

	while (1){
		c++;
		if (c % MILLION == 0)
			printf ("2:  after million iterations\n");
	}
}

int main(){


	pthread_t our_thread1;
	pthread_t our_thread2;
	int result;


	result = pthread_create (&our_thread1, NULL, thread_func1, NULL);
	if (result != 0)
		printf ("thread not created successfully");


	result = pthread_create (&our_thread2, NULL, thread_func2, NULL);
	if (result != 0)
		printf ("thread not created successfully");



	pthread_join (our_thread1, NULL);
	pthread_join (our_thread2, NULL);

	return 0;
}

My Output looks like this:

are we in thread 1?
are we in thread 2?
2:  after million iterations
2:  after million iterations
2:  after million iterations
2:  after million iterations
2:  after million iterations
2:  after million iterations
2:  after million iterations
2:  after million iterations
2:  after million iterations
2:  after million iterations

And I never get anything from thread 1.  Although the program tells us we
have reached thread 1 I never get a thing from it.

I thought that this might be a thread scheduler priority issue and tried the
command pthread_setscheduler() command to change the priority of the threads
but GAH... It immediately seg faulted at that command.

Does anyone out there know if this is in fact a bug, or the correct nature
of NGPT, or I am doing something wrong?

Definitely losing sleep over sleep();
