Synopsis

#include <audio/audiolib.h>

void AuReadElement(server, flow, element, num_bytes, data, status)

AuServer *server;

AuFlowID flow;

AuPointer 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 ExportClient element to read the data from.

num_bytes: Specifies the number of bytes of audio data to read.

data: Specifies the buffer to read the audio data into.

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

Description

AuReadElement transfers audio data from the server to the client application, reading num_bytes from the ExportClient specified by element in audio flow flow into data.
