CMsgThread::WaitForThreadExit (Windows Embedded CE 6.0)
1/6/2010
Blocks until the thread exits.
Syntax
BOOL WaitForThreadExit(
LPDWORD lpdwExitCode
);
Parameters
- lpdwExitCode
Exit code returned by the thread.
Return Value
Returns either TRUE or FALSE, the meaning of which is determined by the class supplying the overridden CMsgThread::ThreadMessageProc member function and the calling member function.
Remarks
Be sure the worker thread has exited completely before completing the destruction of your derived class; otherwise, the thread might still execute after your dynamic-link library (DLL) has been unloaded from the address space of the process.
Even if the only instruction left to exit is a single-return instruction, this would cause an exception.
The only reliable way to ensure that the thread has exited is to signal the thread to exit (using a privately negotiated CMsg object sent to the CMsgThread::PutThreadMsg member function) and then call this member function.
Do this in the destructor for your derived class.
