AuElement(3)						     Library Functions Manual						      AuElement(3)

Name
       AuElement - AuElement union

Structures
       #include <audio/audiolib.h>

       typedef union _AuElement
       {
	   unsigned short type;
	   AuElementImportClient importclient;
	   AuElementImportDevice importdevice;
	   AuElementImportBucket importbucket;
	   AuElementImportWaveForm importwaveform;
	   AuElementBundle bundle;
	   AuElementMultiplyConstant multiplyconstant;
	   AuElementAddConstant addconstant;
	   AuElementSum sum;
	   AuElementExportClient exportclient;
	   AuElementExportDevice exportdevice;
	   AuElementExportBucket exportbucket;
	   AuElementExportMonitor exportmonitor;
       }AuElement;

Members
       type	 Specifies  the  element type.	Currently, one of these constants: AuElementTypeAddConstant, AuElementTypeBundle, AuElementTypeEx-
		 portBucket, AuElementTypeExportClient, AuElementTypeExportDevice, AuElementTypeExportMonitor,	AuElementTypeImportClient,  AuEle-
		 mentTypeImportDevice, AuElementTypeImportBucket, AuElementTypeImportWaveForm, AuElementTypeMultiplyConstant, or AuElementTypeSum.

       importclient
		 Used to read audio data from a client application.

       importdevice
		 Used to read audio data from a device.

       importbucket
		 Used to read audio data from a bucket.

       importwaveform
		 Used to read audio data from a waveform generator.

       bundle	 Used to access tracks in audio data.

       multiplyconstant
		 Used to scale the value of samples in audio data.

       addconstant
		 Used to offset the value of samples in audio data.

       sum	 Used to merge together samples from different inputs.

       exportclient
		 Used to write audio data to a client application.

       exportdevice
		 Used to write audio data to a device.

       exportbucket
		 Used to write audio data to a bucket.

       exportmonitor
		 Used to write monitor data to a client application.

Description
       Elements are instructions to the server on how to handle the audio data in a flow.

Name
       AuMakeElementImportWaveForm - initialize an ImportWaveForm element

Synopsis
       #include <audio/audiolib.h>

       AuMakeElementImportWaveForm(element, sample_rate, wave_form, num_samples, freq, num_actions, actions)
	   AuElement *element; /* RETURN */
	   unsigned short sample_rate;
	   int wave_form;
	   AuInt32 freq;
	   AuInt32 num_samples;
	   int num_actions;
	   AuElementAction *actions;

Arguments
       element	 Returns the initialized element.

       sample_rate
		 Specifies the sample rate of the audio data.

       wave_form Specifies  the waveform to use.  Currently, the following waveforms are defined: AuWaveFormSquare, AuWaveFormSine, AuWaveFormSaw,
		 and AuWaveFormConstant.

       freq	 Specifies the frequency of the waveform.

       num_samples
		 Specifies the number of samples to read.  Use AuUnlimitedSamples to indicate an unlimited number of samples.

       num_actions
		 Specifies the number of actions in actions.

       actions	 Specifies the list of actions to associate with this element.	Entries in this list can be initialized with  AuMakeChangeStateAc-
		 tion, AuMakeSendNotifyAction, and AuMakeNoopAction.  May be NULL.

Description
       AuMakeElementImportWaveForm  sets  the  type  member of element to AuElementTypeImportWaveForm and initializes the importwaveform member of
       element with the remaining arguments.

       AuMakeElementImportWaveForm is implemented as a macro.

NoteS
       A server might not support all the waveforms currently defined.
