Destructor

void Broadcast()

void Signal()

void Wait()

BooleanT Wait(RealT maxTime)

Wait for conditional.
This unlocks the mutex and then waits for a signal. from either Signal, Broadcast or timeout, when it get it the mutex is re-locked and control returned to the program.

Returns false, if timeout occures.

BooleanT Lock(void)

Lock mutex.

BooleanT TryLock(void)

Try and lock mutex.

BooleanT Unlock(void)

Unlock mutex.

void Error(const char * msg)

Report an error.

void Error(const char * msg,int anerrno)

Report an error, with an error number.
