Detailed Description

Platform independent condition variable.

Instances of DtCondVar are used to provide a platform independent condition variable mechanism for use by threads of the same process. Do not use this class to implement inter-process comm- unication between threads of different processes.

Constructor & Destructor Documentation

DtCondVar__rti__::DtCondVar__rti__

(

MAKRti::DtMutex__rti__ *

condMutex

)

constructor

DtCondVar__rti__::DtCondVar__rti__ ( const DtCondVar__rti__ &  orig )

protected

copy constructor

virtual DtCondVar__rti__::~DtCondVar__rti__ ( )

virtual

destructor

Member Function Documentation

virtual void DtCondVar__rti__::broadcast ( )

virtual

signal all waiting processes that the condition has been met

virtual void DtCondVar__rti__::destroy ( )

virtual

destroy the condition variable.

This should only be called when no threads or processes will access the condition variable any longer.

virtual void DtCondVar__rti__::init ( )

virtual

initialize condition variable

Reimplemented in DtIpcCondVar__rti__.

const DtCondVar__rti__& DtCondVar__rti__::operator= ( const DtCondVar__rti__ &  orig )

protected

assignment operator

virtual void DtCondVar__rti__::signal ( )

virtual

signal next waiting process that the condition has been met

virtual int DtCondVar__rti__::wait ( DtTime  waitTime = 0.0 )

virtual

wait for the condition to be met.

Returns 0 if condition met, +1 if timeout occured, -1 if error
