Gunnar Beutner	b3eb55ec9a	LibPthread: Implement sem_getvalue()	2021-04-15 09:31:49 +02:00
Gunnar Beutner	a44ddc4793	LibPthread: Don't hold sem->mtx after sem_wait()/sem_trywait() ... Semaphores with values greater than one didn't work because whoever called sem_wait() first held the semaphore's mutex until a matching sem_post() call. Other callers then wouldn't be able to acquire the semaphore even if the semaphore's value was still greater than zero at that point.	2021-04-15 09:31:49 +02:00
Gunnar Beutner	32794e00a1	LibPthread: Improve error handling for the semaphore functions ... This patch makes sure we're propagating errors to the caller.	2021-04-15 09:31:49 +02:00
Gunnar Beutner	98403eccb0	LibPthread: Ensure we're not overflowing the semaphore's value	2021-04-15 09:31:49 +02:00
