waveInGetDevCaps

This function retrieves the capabilities of a specified waveform-audio input device.

MMRESULT waveInGetDevCaps(
UINT uDeviceID, 
LPWAVEINCAPS pwic, 
UINT cbwic ); 

Parameters

  • uDeviceID
    Identifier of the waveform-audio output device. It can be either a device identifier or a Handle to an open waveform-audio input device.
  • pwic
    Pointer to a WAVEINCAPS structure to be filled with information about the capabilities of the device.
  • cbwic
    Size, in bytes, of the WAVEINCAPS structure.

Return Values

One of the values described in the following table is returned.

Value Description
MMSYSERR_NOERROR Success.
MMSYSERR_BADDEVICEID Specified device identifier is out of range.
MMSYSERR_NODRIVER No device driver is present.
MMSYSERR_NOMEM Unable to allocate or lock memory.

Remarks

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.
