~FXCondition () |
A condition allows one or more threads to synchronize to an event.
When a thread calls wait, the associated mutex is unlocked while the thread is blocked. When the condition becomes signaled, the associated mutex is locked and the thread(s) are reawakened.
Initialize the condition.
Delete the condition.
void FX::FXCondition::wait | ( | FXMutex & | mtx | ) |
Wait until condition becomes signalled, using given mutex, which must already have been locked prior to this call.
FXbool FX::FXCondition::wait | ( | FXMutex & | mtx, |
FXlong | nsec | ||
) |
Wait until condition becomes signalled, using given mutex, which must already have been locked prior to this call.
Returns TRUE if successful, FALSE if timeout occurred. Note that the wait-time is specified in nanoseconds since the Epoch (Jan 1, 1970).
void FX::FXCondition::signal | ( | ) |
Wake or unblock a single blocked thread.
void FX::FXCondition::broadcast | ( | ) |
Wake or unblock all blocked threads.
