- server
- Specifies the connection to the audio server.
- 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, AuCompDeviceGainMask,
AuCompDeviceLineModeMask, AuCompDeviceChildrenMask, or AuCompDeviceMasks.
If valuemask is zero, the attributes are ignored and are not referenced.
- 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.
- status
- If non-NULL, flush the output buffer and return
the status from the server.
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.
