WAVEINCAPS

The WAVEINCAPS structure describes the capabilities of a waveform-audio input device.

typedef struct { 
    WORD      wMid; 
    WORD      wPid; 
    MMVERSION vDriverVersion; 
    CHAR      szPname[MAXPNAMELEN]; 
    DWORD     dwFormats; 
    WORD      wChannels; 
    WORD      wReserved1; 
} WAVEINCAPS; 
 

Members

wMid

Manufacturer identifier for the device driver for the waveform-audio input device. Manufacturer identifiers are defined in Manufacturer and Product Identifiers.

wPid

Product identifier for the waveform-audio input device. Product identifiers are defined in Manufacturer and Product Identifiers.

vDriverVersion

Version number of the device driver for the waveform-audio input device. The high-order byte is the major version number, and the low-order byte is the minor version number.

szPname

Product name in a null-terminated string.

dwFormats

Standard formats that are supported. Can be a combination of the following:

Format	Description
WAVE_FORMAT_1M08	11.025 kHz, mono, 8-bit
WAVE_FORMAT_1M16	11.025 kHz, mono, 16-bit
WAVE_FORMAT_1S08	11.025 kHz, stereo, 8-bit
WAVE_FORMAT_1S16	11.025 kHz, stereo, 16-bit
WAVE_FORMAT_2M08	22.05 kHz, mono, 8-bit
WAVE_FORMAT_2M16	22.05 kHz, mono, 16-bit
WAVE_FORMAT_2S08	22.05 kHz, stereo, 8-bit
WAVE_FORMAT_2S16	22.05 kHz, stereo, 16-bit
WAVE_FORMAT_4M08	44.1 kHz, mono, 8-bit
WAVE_FORMAT_4M16	44.1 kHz, mono, 16-bit
WAVE_FORMAT_4S08	44.1 kHz, stereo, 8-bit
WAVE_FORMAT_4S16	44.1 kHz, stereo, 16-bit

wChannels

Number specifying whether the device supports mono (1) or stereo (2) input.

wReserved1

Padding.
