Constructor & Destructor Documentation

MMutexLock::MMutexLock

Member Function Documentation

void MMutexLock::lock

(

)

Create a lock. If the mutex is available it is locked immediately. If it is already locked by another thread, this function waits until the other thread has unlocked it, then creates the lock.

void MMutexLock::unlock

(

)

Release the current lock on a mutex.

bool MMutexLock::tryLock

(

)

Attempt to lock the mutex. If the mutex is already locked by another thread, the function returns right away.

Returns:

• true lock was obtained
• false lock was not obtained
