if((sem_init(sem, 1, 1)) == 1) perror("error initiating sem");

If I include this line of code my program simply starts and exits. I just started learning how to use semaphores. I'm using cygwin and when this line is commented out the printf's ABOVE this print to console but when include this, nothing happens.

I did the following to get cygserver going-

CYGWIN=server
ran /bin/cygserver-config
ran /usr/sbin/cygserver

for the config it said the cygserver is already running And for the sygserver it saids-

initailaizing complete
failed to created named pipe: is the daemon already running?
fatal error on IPC transport: closing down

Any ideas?
