Hi, All

I'm now involved in a networking porting project. I use CFRunLoop to simulate

WaitForMultipleObjects (API on Windows platform), but the following function works

only when just one runloopsource is registered with the runloop. When more than

one runloopsource are registered, it always timeout... What should I do?

Any tips are highly appreciated. thanks in advance.

DWORD WaitForMultipleObjects(DWORD nCount, const HANDLE* lpHandles,
BOOL bWaitAll, DWORD dwMilliseconds)
{
PENCAP_EVENT *eventPointerArray = (PENCAP_EVENT *)lpHandles;
CFRunLoopRef curRunLoop = CFRunLoopGetCurrent();
int cnt;
for(cnt = 0; cnt < nCount; cnt++) {
CFRunLoopAddSource(curRunLoop, eventPointerArray[cnt]->source, kCFRunLoopCommonModes);
}

// Run the CFRunLoop kCFRunLoopDefaultMode
SInt32 result = CFRunLoopRunInMode(kCFRunLoopDefaultMode, (dwMilliseconds/1000), true);

// Remove RunLoopSource
for(cnt = 0; cnt < nCount; cnt++) {
CFRunLoopRemoveSource(curRunLoop, eventPointerArray[cnt]->source, kCFRunLoopCommonModes);
}

if(result == kCFRunLoopRunTimedOut) {
  // timeout
  return WAIT_TIMEOUT;
}
if(result != kCFRunLoopRunHandledSource) {
  // wait failed
  return WAIT_FAILED;
}
