This 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.

  • wPid
    Product identifier for the waveform-audio input device.

  • 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
    Null-terminated string that contains the product name.

    The length of szPname is defined by the following macro in Mmsystem.h:

    #define MAXPNAMELEN 32 /* max product name length (including NULL) */

  • dwFormats
    Specifies the standard formats that are supported. It is one or a combination of the following flags.

    Flag 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 that specifies whether the device supports mono (1) or stereo (2) input.

  • wReserved1
    Padding.

Remarks

Manufacturer and product identifiers are used in Windows-based desktop systems to allow applications to determine which devices are installed on a host computer. Although these identifiers are supported in Windows CE, they are rarely needed or used because embedded devices typically have built-in devices with built-in drivers.

Requirements

OS Versions: Windows CE 2.0 and later.
Header: Mmsystem.h.
