Declaration
virtual kern_return_t HandleChangeSampleRate(double in_sample_rate);Parameters
- in_sample_rate:
The sample rate to set, if possible, as a
double.
Return Value
kIOReturnSuccess on success, or another value if an error occurs. For a list of error codes, see Error Codes.
Discussion
The default implementation calls SetSampleRate and returns kIOReturnSuccess. Subclass and override this method to handle changes to the sample rate and return kIOReturnSuccess upon success.
