AuMakeElementExportClient

Name

AuMakeElementExportClient - initialize an ExportClient element

Synopsis

#include <audio/audiolib.h> AuMakeElementExportClient(element, input, sample_rate, format, num_tracks, discard, max_samples, high_water_mark, num_actions, actions)
AuElement *element; /* RETURN */
unsigned short input;
unsigned short sample_rate;
unsigned char format;
unsigned char num_tracks;
unsigned char discard;
AuUint32 max_samples;
AuUint32 high_water_mark;
int num_actions;
AuElementAction *actions;

Arguments

element

Returns the initialized element.

input

Specifies the index of the element to supply the audio data to this element.

sample_rate

Specifies the sample rate of the audio data.

format

Specifies the format of the audio data. Currently, the following formats are defined: AuFormatULAW8, AuFormatLinearUnsigned8, AuFormatLinearSigned8, AuFormatLinearSigned16MSB, AuFormatLinearUnsigned16MSB, AuFormatSignedLinear16LSB, and AuFormatLinearUnsigned16LSB.

num_tracks

Specifies the number of tracks in the audio data.

discard

Specifies if the flow should pause initially. Normally AuTrue.

max_samples

Specifies the maximum number of samples to send to the client in a single write. Ignored for "trivial" flows.

high_water_mark

Specifies when to tell the client application to read the audio data from the server. When this number of samples is reached in the buffer, an ElementNotify event with kind set to AuElementNotifyKindHighWater will be sent to the client application.

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 AuMakeChangeStateAction, AuMakeSendNotifyAction, and AuMakeNoopAction. May be NULL.

Description

AuMakeElementExportClient sets the type member of element to AuElementTypeExportClient and initializes the exportclient member of element with the remaining arguments. AuMakeElementExportClient is implemented as a macro.
