Detailed Description

This class starts a read operation for the PReadWriteMutex on construction and automatically ends the read operation on destruction.

This is very usefull for constructs such as:

    void func()
    {
      PReadWaitAndSignal mutexWait(myMutex);
      if (condition)
        return;
      do_something();
      if (other_condition)
        return;
      do_something_else();
    }

Constructor & Destructor Documentation

PReadWaitAndSignal::PReadWaitAndSignal ( const PReadWriteMutex &  mutex, bool  start = true  )

inline

Create the PReadWaitAndSignal wait instance.

This will wait on the specified PReadWriteMutex using the StartRead() function before returning.

Parameters

mutex	PReadWriteMutex descendent to wait/signal.
start	Start read operation on PReadWriteMutex before returning.
