AuMakeElementExportClient(3) Library Functions Manual AuMakeElementExportClient(3)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 AuFormatLinearUn-
signed16LSB.
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 AuMakeChangeStateAc-
tion, 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.
