MMRESULT waveInAddBuffer( HWAVEIN hwi, LPWAVEHDR pwh, UINT cbwh );
Handle to the waveform-audio input device.
Pointer to a WAVEHDR structure that identifies the buffer.

Returns MMSYSERR_NOERROR if successful or an error otherwise. Possible error values include the following.
||Specified device handle is invalid.|
||No device driver is present.|
||Unable to allocate or lock memory.|
