HwProgramLatencyTimer
Sets the amount of time to wait before sending the current buffer to the device.
Declaration
virtual kern_return_t HwProgramLatencyTimer(uint32_t latency);Parameters
- latency:
The number of milliseconds for the device to wait before sending a partial buffer to the host.
Return Value
kIOReturnSuccess on success, or another value if an error occurs. See Error Codes.
Discussion
Override this method and use it to configure a latency timer for the device. Rather than sending buffers only when they’re full, the latency timer ensures that the hardware sends any accumulated data at the specified interval.
