Multithreaded Win32 GUI message loop
- by Dave18
When do you need to use this type of modified message loop in multithreaded application?
DWORD nWaitCount;
HANDLE hWaitArray[4];
BOOL quit;
int exitCode;
while (!quit)
{
MSG msg;
int rc;
rc = MsgWaitForMultipleObjects(nWaitCount, hWaitArray, FALSE, INFINITE,QS_ALLINPUT);
if (rc == WAIT_OBJECT_O + nWaitCount)
{
while (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
if (msg.message == WM_QUIT)
{
quit = TRUE;
exitCode = msg.wParam;
break;
}
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
else if (rc >= WAIT_OBJECT_0 && rc < WAIT_OBJECT_0 + nwaitCount)
{
int nlndex = rc - WAIT_OBJECT_0;
}
else if (rc >= WAIT_ABANDONED_0 && rc < WAIT_ABANDONED_0+ nWaitCount)
{
int nlndex = rc - WAIT_ABANDONED_O;
}
}
