MMRESULT waveInStart(
Parameters
hwi
Handle of the waveform-audio input device.

Remarks
Buffers are returned to the application when full or when the waveInReset function is called (the dwBytesRecorded member in the header will contain the length of data). If there are no
buffers in the queue, the data is thrown away without notifying the application, and
input continues.
Calling this function when input is already started has no effect, and the
function returns zero.
