Detailed Description
An object oriented wrapper around a non recursive mutex.
A mutex can only be unlock()'ed, by the thread which lock()'ed it. A trylock is a non blocking lock action which fails or succeeds.
- Warning:
- Mutex instances should only be created in soft realtime, since the initialisation of a mutex can not be done in hard realtime.
- See also:
- MutexLock, MutexTryLock, MutexTimedLock, MutexRecursive

Member Function Documentation
| virtual bool RTT::os::Mutex::timedlock | ( | Seconds | s | ) | [inline, virtual] |
Lock this mutex, but don't wait longer for the lock than the specified timeout.
- Parameters:
-
s The maximum time to wait before aqcuiring the lock.
- Returns:
- true when the locking succeeded, false otherwise
Implements RTT::os::MutexInterface.
| virtual bool RTT::os::Mutex::trylock | ( | ) | [inline, virtual] |
Try to lock this mutex.
- Returns:
- true when the locking succeeded, false otherwise
