.SH \fBArguments\fP
.IP \fIserver\fP 1i
Specifies the connection to the audio server.
.IP \fIvaluemask\fP 1i
Specifies which device attributes are defined in the attributes argument.
This must be a bitwise inclusive OR of zero or more of these constants: \fBAuCompCommonIDMask\fP, \fBAuCompCommonKindMask\fP, \fBAuCompCommonUseMask\fP, \fBAuCommonFormatMask\fP, \fBAuCommonNumTracksMask\fP, \fBAuCommonAccessMask\fP, \fPAuCommonDescriptionMask\fP, \fBAuCompDeviceMinSampleRateMask\fP, \fBAuCompDeviceMaxSampleRateMask\fP, \fBAuCompDeviceLocationMask\fP, \fBAuCompDeviceGainMask\fP, \fBAuCompDeviceLineModeMask\fP, \fBAuCompDeviceChildrenMask\fP, or \fBAuCompDeviceMasks\fP.
If valuemask is zero, the attributes are ignored and are not referenced.
.IP \fIattributes\fP 1i
Specifies the structure from which the values (as specified by the value mask) are to be taken.
.IP \fIndevices\fP 1i
Returns the number of devices in the returned list.
.IP \fIstatus\fP 1i
If non-NULL, flush the output buffer and return the status from the server.
.SH \fBDescription\fP
\fBAuListDevices\fP returns a list of devices whose attributes match those values in \fIattributes\fP specified by \fIvaluemask\fP, or NULL, with \fIndevices\fP set to 0, if there was an error.
Use \fBAuFreeDeviceList\fP to release the memory in the list when its nolonger needed.
