Detailed Description

Is a mutex which can be queried via its lock mode. See isLocked().

Example

void MyClass::makeAnyThing()
{
  m_MyCriticalSection->lock();
  // An access from a thread to m_pMyPrivateClass->makeManyThings() via this
  // method prevents other threads from accessing this method (or other methods
  // secured with m_MyLocalCriticalSection) before the CriticalSection is
  // finished with unlock() from the first thread.
  this->makeManyThings();
  // catch an exception here if one can be thrown.
  m_MyCriticalSection->unlock();
}
