Members

Do not dereference the members of the AuDeviceAttributes structure directly. Instead use the access macros.

da is a pointer to a AuDeviceAttributes structure.

AuDeviceValueMask(da)
Accesses the AuMask value indicating what attributes are present. This is a bitwise inclusive OR of these constants: AuCompCommonIDMask, AuCompCommonKindMask, AuCompCommonUseMask, AuCompCommonFormatMask, AuCompCommonNumTracksMask, AuCompCommonAccessMask, AuCompCommonDescriptionMask, AuCompDeviceMinSampleRateMask, AuCompDeviceMaxSampleRateMask, AuCompDeviceLocationMask, AuCompDeviceGainMask, AuCompDeviceLineModeMask, and AuCompDeviceChildrenMask.
AuDeviceChangableMask(da)
Accesses the AuMask value indicating which attributes can be changed. This is a bitwise inclusive OR of these constants: AuCompCommonIDMask, AuCompCommonKindMask, AuCompCommonUseMask, AuCompCommonFormatMask, AuCompCommonNumTracksMask, AuCompCommonAccessMask, AuCompCommonDescriptionMask, AuCompDeviceMinSampleRateMask, AuCompDeviceMaxSampleRateMask, AuCompDeviceLocationMask, AuCompDeviceGainMask, AuCompDeviceLineModeMask, and AuCompDeviceChildrenMask.
AuDeviceIdentifier(da)
Accesses the AuFlowID ID of the device.
AuDeviceKind(da)
Accesses the int value indicating the kind of component. Devices are either AuComponentKindPhysicalInput or AuComponentKindPhysicalOutput.
AuDeviceUse(da)
Accesses the AuMask value indicating what uses of the device are permitted. This is a bitwise inclusive OR of these constants: AuComponentUseImportMask and AuComponentUseExportMask.
AuDeviceFormat(da)
Accesses the int value indicating the audio data format the device uses. Currently, the following formats are defined: AuFormatULAW8, AuFormatLinearUnsigned8, AuFormatLinearSigned8, AuFormatLinearSigned16MSB, AuFormatLinearUnsigned16MSB, AuFormatLinearSigned16LSB, and AuFormatLinearUnsigned16LSB.
AuDeviceNumTracks(da)
Accesses the int value indicating the number of tracks the device supports.
AuDeviceAccess(da)
Accesses the AuMask value indicating what kinds of access are allowed. This is a bitwise inclusive OR of these constants: AuAccessImportMask, AuAccessExportMask, AuAccessDestroyMask, and AuAccessListMask.
AuDeviceDescription(da)
Accesses the AuString structure containing a textual description of the device.
AuDeviceMinSampleRate(da)
Accesses the unsigned int value indicating the minimum sample rate supported by the device.
AuDeviceMaxSampleRate(da)
Accesses the unsigned int value indicating the maximum sample rate supported by the device.
AuDeviceLocation(da)
Accesses the AuMask value indicating the location of the device. This is a bitwise inclusive OR of these constants: AuDeviceLocationLeftMask, AuDeviceLocationCenterMask, AuDeviceLocationRightMask, AuDeviceLocationTopMask, AuDeviceLocationMiddleMask, AuDeviceLocationBottomMask, AuDeviceLocationBackMask, AuDeviceLocationFrontMask, AuDeviceLocationInternalMask, and AuDeviceLocationExternalMask
AuDeviceGain(da)
Accesses the AuFixedPoint value with the current hardware amplification level.
AuDeviceLineMode(da)
Accesses the AuInt32 value indicating the current line mode (input device only).
AuDeviceNumChildren(da)
Accesses the int value indicating the number of subcomponents of the device.
AuDeviceChildren(da)
Accesses the list of AuDeviceID's of the subcomponents of the device.

Description

The AuDeviceAttributes structure describes the physical hardware interface.
