AudioDeviceStart(_:_:)

Declaration

func AudioDeviceStart(_ inDevice: AudioObjectID, _ inProcID: AudioDeviceIOProcID?) -> OSStatus

Parameters

• inDevice:

  The AudioDevice to start the IOProc on.

• inProcID:

  The AudioDeviceIOProcID to start. Note that this can be NULL, which starts the hardware regardless of whether or not there are any IOProcs registered. This is necessary if any of the AudioDevice’s timing services are to be used. A balancing call to AudioDeviceStop with a NULL IOProc is required to stop the hardware.

Return Value

An OSStatus indicating success or failure.

Discussion

Starts IO for the given AudioDeviceIOProcID.
