Hi! The following code sequence fails (does not wait): sem_t sem; sem_init(&sem, 0, 0); sem_wait(&sem); I believe the reason is found in ./winsup/cygwin/thread.cc line 437 (20001228 snapshot): item->win32_obj_id = ::CreateSemaphore (&sec_none_nih, _v, _v, NULL); The third parameter is the maximum count for the semaphore, and it is not allowed to be zero or less according to Microsofts documentation. If I replace this line with item->win32_obj_id = ::CreateSemaphore (&sec_none_nih, _v, LONG_MAX, NULL); the above example works just fine. If possible, I would like a comment on this.
