示例1: AudioHardwareStreamPropertyChanged

void	HP_Stream::PropertiesChanged(UInt32 inNumberAddresses, const AudioObjectPropertyAddress inAddresses[]) const
{
    //	note that we need to be sure that the object state mutex is not held while we call the listeners
    bool ownsStateMutex = false;
    CAMutex* theObjectStateMutex = const_cast<HP_Object*>(this)->GetObjectStateMutex();
    if(theObjectStateMutex != NULL)
    {
        ownsStateMutex = theObjectStateMutex->IsOwnedByCurrentThread();
        if(ownsStateMutex)
        {
            theObjectStateMutex->Unlock();
        }
    }
        
    for(UInt32 theIndex = 0; theIndex < inNumberAddresses; ++theIndex)
    {
        OSStatus theError = AudioHardwareStreamPropertyChanged(mPlugIn->GetInterface(), mOwningDevice->GetObjectID(), mObjectID, inAddresses[theIndex].mElement, inAddresses[theIndex].mSelector);
        AssertNoError(theError, "HP_Stream::PropertiesChanged: got an error calling the input listeners");
    }
        
    //	re-lock the mutex
    if((theObjectStateMutex != NULL) && ownsStateMutex)
    {
        theObjectStateMutex->Lock();
