MIXERCAPS structure

The MIXERCAPS structure describes the capabilities of a mixer device.

Syntax


typedef struct {
  WORD      wMid;
  WORD      wPid;
  MMVERSION vDriverVersion;
  TCHAR     szPname[MAXPNAMELEN];
  DWORD     fdwSupport;
  DWORD     cDestinations;
} MIXERCAPS;

Members

wMid

A manufacturer identifier for the mixer device driver. Manufacturer identifiers are defined in Manufacturer and Product Identifiers.

wPid

A product identifier for the mixer device driver. Product identifiers are defined in Manufacturer and Product Identifiers.

vDriverVersion

Version number of the mixer device driver. The high-order byte is the major version number, and the low-order byte is the minor version number.

szPname

Name of the product. If the mixer device driver supports multiple cards, this string must uniquely and easily identify (potentially to a user) the specific card.

fdwSupport

Various support information for the mixer device driver. No extended support bits are currently defined.

cDestinations

The number of audio line destinations available through the mixer device. All mixer devices must support at least one destination line, so this member cannot be zero. Destination indexes used in the dwDestination member of the MIXERLINE structure range from zero to the value specified in the cDestinations member minus one.

Requirements

Windows 2000 Professional [desktop apps only]
