MIXERCAPS
The MIXERCAPS structure describes the capabilities of a mixer device.
typedef struct {
WORD wMid;
WORD wPid;
MMVERSION vDriverVersion;
CHAR 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.
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.
