	Quick Info

The waveInStart function starts input on the given waveform-audio input device.

MMRESULT waveInStart(

HWAVEIN hwi
);

Parameters
hwi

Handle of the waveform-audio input device.

Return Values
Returns MMSYSERR_NOERROR if successful or an error otherwise. Possible error values include the following:

MMSYSERR_INVALHANDLE	Specified device handle is invalid.
MMSYSERR_NODRIVER	No device driver is present.
MMSYSERR_NOMEM	Unable to allocate or lock memory.

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.
