WAVEINCAPS structure

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

Syntax


typedef struct {
  WORD      wMid;
  WORD      wPid;
  MMVERSION vDriverVersion;
  TCHAR     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:
