| * Test that pthread_rwlock_unlock(pthread_rwlock_t *rwlock) |
| * |
| * It 'may' fail if: |
| * [EINVAL] rwlock doesn't refer to an intialized read-write lock |
| * [EPERM] the current thread doesn't hold the lock on the rwlock |
| * |
| * Testing EINVAL in this test. |
| * |
| * Steps: |
| * 1. Call pthread_rwlock_unlock with an uninitialized rwlock |
| * 2. The test will pass even if it returns 0, but with a note stating that the standard |
| * states it 'may' fail. |
