Result = TryLockMutex(Mutex)Description
Tries to lock the specified mutex. Unlike LockMutex(), this function does not stop execution until the mutex is available. It returns immediately and the return-value indicates if the lock was successful or not. This is useful in situations were the thread should not wait for the mutex to be available but rather do other things in the meantime.
Mutex The mutex to lock.
Nonzero if the mutex was successfully locked, zero otherwise.
If the lock was successful, the UnlockMutex() function must be called to make the mutex available to other threads again. If this is not done, this could easily lead to a lockup situation.
