Detailed Description

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

This is very useful for constructs such as:

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

Constructor & Destructor Documentation

PWriteWaitAndSignal::PWriteWaitAndSignal	(	const PReadWriteMutex &	rw,
		PBoolean	start = true
	)

Create the PWriteWaitAndSignal wait instance.

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

Parameters:

rw	PReadWriteMutex descendent to wait/signal.
start	Start write operation on PReadWriteMutex before returning.

PWriteWaitAndSignal::~PWriteWaitAndSignal

(

)

End write operation on the PReadWriteMutex.

This will execute the EndWrite() function on the PReadWriteMutex that was used in the construction of this instance.
