AuWriteElement(3)					     Library Functions Manual						 AuWriteElement(3)

Name
       AuWriteElement - write data to an ImportClient element in a flow

Synopsis
       #include <audio/audiolib.h>

       void AuWriteElement(server, flow, element, num_bytes, data, end_of_data, status)
	   AuServer *server;
	   AuFlowID flow;
	   int element;
	   AuUint32 num_bytes;
	   AuPointer data;
	   AuBool end_of_data;
	   AuStatus *status; /* RETURN */

Arguments
       server	 Specifies the connection to the audio server.

       flow	 Specifies the ID of the flow.

       element	 Specifies the index of the ImportClient element to write the data to.

       num_bytes Specifies the number of bytes of audio data to write.

       data	 Specifies the buffer to get the audio data from.

       end_of_data
		 Specifies if this is the last write for this import.

       status	 If non-NULL, flush the output buffer and return the status from the server.

Description
       AuWriteElement transfers audio data from the client application to the server, writing num_bytes from data to the ImportClient specified by
       element in the audio flow flow.	If end_of_data is AuTrue, the ImportClient's eof flag will be set when the write is completed.

Note
       If the flow is "trivial" (consisting only of an ImportClient and an ExportBucket), the num_samples fields in the ImportClient  and  Export-
       Bucket are ignored and a write past the end of the bucket will result in an AuBadLength error.

Errors
       AuBadFlow, AuBadElement, AuBadValue, AuBadLength.

Name
       AuSoundRecord - create a flow to record audio to any destination.

Synopsis
       #include <audio/audiolib.h>
       #include <audio/soundlib.h>

       AuEventHandlerRec *AuSoundRecord(server, source, gain, num_samples, mode, sound_data, flow, volume_mult_elem, status)
	   AuServer *server;
	   AuDeviceID source;
	   AuFixedPoint gain;
	   AuUint32 num_samples;
	   int mode;
	   AuSoundDataPtr sound_data;
	   AuFlowID *flow; /* RETURN */
	   int *volume_mult_elem; /* RETURN */
	   AuStatus *status; /* RETURN */

Arguments
       server	 Specifies the connection to the audio server.

       source	 Specifies the input device to use.

       gain	 Specifies the gain for the input device.

       num_samples
		 Specifies the number of samples to record.

       mode	 Specifies the line mode for the input device.	Currently the following line modes are defined: AuDeviceInputModeNone, AuDeviceIn-
		 putModeLineIn, AuDeviceInputModeMicrophone.

       sound_data
		 Specifies the sound information.

       flow	 If non-NULL, returns the flow ID.

       volume_mult_elem
		 Accord to the comment in the source, not implemented.

       status	 If non-NULL, flush the output buffer and return the status from the server.

Description
       AuSoundRecord creates a flow to record audio from source to any destination and returns a pointer to the event handler created or  NULL	if
       there was an error. The sound_data structure contains the necessary information about the audio format and the data handling function.

Errors
       AuBadDevice.
