valuemask Specifies which device attributes are defined in
the attributes argument. This must be a bitwise
inclusive OR of zero or more of these constants:
AuCompCommonIDMask, AuCompCommonKindMask, AuCompCommonUseMask,
AuCommonFormatMask, AuCommonNumTracksMask,
AuCommonAccessMask, AuCommonDescriptionMask,
AuCompDeviceMinSampleRateMask, AuCompDeviceMaxSampleRateMask,
AuCompDeviceLocationMask,
attributes
Specifies the structure from which the values
(as specified by the value mask) are to be
taken.
ndevices Returns the number of devices in the returned list.
AuListDevices returns a list of devices whose attributes match those values in attributes specified by valuemask, or NULL, with ndevices set to 0, if there was an error. Use AuFreeDeviceList to release the memory in the list when its nolonger needed.
