Rich Felker	3d8d90c5cc	sem_open should make process-shared semaphores this did not matter because we don't yet treat process-shared special. when private futex support is added, however, it will matter.	14 years ago
Rich Felker	39f296a95b	use O_CLOEXEC to open semaphore files in sem_open	14 years ago
Rich Felker	6e53a6eca4	fix useless use of potentially-uninitialized mode variable in sem_open	15 years ago
Rich Felker	682a0f271f	fix failure behavior of sem_open when sem does not exist	15 years ago
Rich Felker	81af503610	fix sem_open and sem_close to obey posix semantics multiple opens of the same named semaphore must return the same pointer, and only the last close can unmap it. thus the ugly global state keeping track of mappings. the maximum number of distinct named semaphores that can be opened is limited sufficiently small that the linear searches take trivial time, especially compared to the syscall overhead of these functions.	15 years ago
Rich Felker	6fc5fdbdc7	implement POSIX semaphores	15 years ago
