Detailed Description

An object oriented wrapper around a 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.

Constructor & Destructor Documentation

RTT::os::MutexRecursive::MutexRecursive ( )

inline

Initialize a recursive Mutex.

Definition at line 227 of file Mutex.hpp.

References rtos_mutex_rec_init().

virtual RTT::os::MutexRecursive::~MutexRecursive ( )

inlinevirtual

Destroy a MutexRecursive.

If the MutexRecursive is still locked, the RTOS will not be asked to clean up its resources.
