WAVEINCAPSW structure (mmeapi.h)

  • Article

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

Syntax

typedef struct tagWAVEINCAPSW {
  WORD      wMid;
  WORD      wPid;
  MMVERSION vDriverVersion;
  WCHAR     szPname[MAXPNAMELEN];
  DWORD     dwFormats;
  WORD      wChannels;
  WORD      wReserved1;
} WAVEINCAPSW, *PWAVEINCAPSW, *NPWAVEINCAPSW, *LPWAVEINCAPSW;

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[MAXPNAMELEN]

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
WAVE_FORMAT_96M08 96 kHz, mono, 8-bit
WAVE_FORMAT_96M16 96 kHz, mono, 16-bit
WAVE_FORMAT_96S08 96 kHz, stereo, 8-bit
WAVE_FORMAT_96S16 96 kHz, stereo, 16-bit

wChannels

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

wReserved1

Remarks

Note

The mmeapi.h header defines WAVEINCAPS as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.

Requirements

Requirement Value
Minimum supported client Windows 2000 Professional [desktop apps only]
Minimum supported server Windows 2000 Server [desktop apps only]
Header mmeapi.h (include Windows.h)
