INKReturnCode INKMutexLock (INKMutex mutexp)

Locks the INKMutex mutexp. If mutexp is already locked, then INKMutexLock blocks until the mutex is unlocked. An INKMutex will be recursively locked if INKMutexLock is called on the same mutex twice from the same thread. Thus, the following example will succeed and not block on the second call to INKMutexLock.

INK_SUCCESS if the mutex is successfully locked.

INK_ERROR if an error occurs.

INKMutexLock (some_mutex);
INKMutexLock (some_mutex);
INKMutexUnlock (some_mutex);
INKMutexUnlock (some_mutex);
