| PTHREAD_MUTEX_ERRORCHECK |
| |
| Provides errorchecking. A thread attempting to relock this mutex without unlocking it |
| first will return with an error. A thread attempting to unlock a mutex which another |
| thread has locked will return with an error. A thread attempting to unlock an unlocked |
| mutex will return with an error. |
| * |
| * Steps: |
| * 1. Initialize a pthread_mutexattr_t object with pthread_mutexattr_init() |
| * 2 Set the 'type' of the mutexattr object to PTHREAD_MUTEX_ERRORCHECK. |
| * 3. Create a mutex with that mutexattr object. |
| * 4. Attempt to unlock an unlocked mutex. It should return an error. |
