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();
}
}
示例2: AudioObjectPropertiesChanged

}
}
OSStatus theError = AudioObjectPropertiesChanged(mPlugIn->GetInterface(), mObjectID, inNumberAddresses, inAddresses);
AssertNoError(theError, "HP_Object::PropertiesChanged: got an error calling the listeners");
// re-lock the mutex
