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:
