Name

       AuListDevices - list devices

Synopsis

       #include <audio/audiolib.h>

       AuDeviceAttributes *AuListDevices(server, valuemask, attributes, ndevices, status)
           AuServer *server;
           AuMask valuemask;
           AuDeviceAttributes *attributes;
           int *ndevices; /* RETURN */
           AuStatus *status; /* RETURN */

Arguments

       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.

Description

       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.

Errors

       AuBadLength.
