Member Function Documentation

Lock()

bool cMutex::Lock	(	int	TimeoutMs = 0,
		bool *	TimedOut = NULL )

Returns true if the mutex was successfully locked.

If TimeoutMs is greater than 0, waits up to the given number of milliseconds before giving up and returning false. If TimeoutMs is 0, waits indefinitely. If TimedOut is given, it will be set to true if the function returns false because of a timeout.
