ctevent.cpp

这是c++编程方面的名著的例子代码

#include "ctevent.h"



event_mutex::event_mutex(char *MName, int Initial, unsigned long Dur)
{

     if(DosCreateEventSem(MName,&EventMutex,0,Initial)){
	EventException.message("Could Not Create Event Semaphore");
	throw EventException;
     }
     EventWait = Dur;
}

void event_mutex::postEvent(void)
{
    DosPostEventSem(EventMutex);

}

void event_mutex::waitEvent(void)
{

   DosWaitEventSem(EventMutex,EventWait);

}

event_mutex::~event_mutex(void)
{

      if(DosCloseEventSem(EventMutex)){
	 EventException.message("Could Not Close Mutex");
	 throw EventException;
      }
}
