waveInStart
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.
