The waveInStart function starts input on the given waveform-audio input device.
MMRESULT waveInStart(
HWAVEIN hwi
);
Returns MMSYSERR_NOERROR if successful or an error otherwise. Possible error values include the following:
| Value | Description | |
|---|---|---|
| MMSYSERR_INVALHANDLE | Specified device handle is invalid. | |
| MMSYSERR_NODRIVER | No device driver is present. | |
| MMSYSERR_NOMEM | Unable to allocate or lock memory. | |
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.
