The waveInGetDevCaps function retrieves the capabilities of a given waveform-audio input device.
MMRESULT waveInGetDevCaps( UINT_PTR uDeviceID, LPWAVEINCAPS pwic, UINT cbwic );
Identifier of the waveform-audio output device. It can be either a device identifier or a handle of an open waveform-audio input device.
Pointer to a WAVEINCAPS structure to be filled with information about the capabilities of the device.
Size, in bytes, of the WAVEINCAPS structure.
Returns MMSYSERR_NOERROR if successful or an error otherwise. Possible error values include the following.
|MMSYSERR_BADDEVICEID||Specified device identifier is out of range.|
|MMSYSERR_NODRIVER||No device driver is present.|
|MMSYSERR_NOMEM||Unable to allocate or lock memory.|
Use this function to determine the number of waveform-audio input devices present in the system. If the value specified by the uDeviceID parameter is a device identifier, it can vary from zero to one less than the number of devices present. The WAVE_MAPPER constant can also be used as a device identifier. Only cbwic bytes (or less) of information is copied to the location pointed to by pwic. If cbwic is zero, nothing is copied and the function returns zero.
