Synopsis

       #include <audio/audiolib.h>

       void AuReadElement(server, flow, element, num_bytes, data, status)
           AuServer *server;
           AuFlowID flow;
           int element;
           AuUint32 num_bytes;
           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.

Note

       If the flow is "trivial" (consisting only of an ExportClient and an ImportBucket), the num_samples fields
       in the ExportClient and ImportBucket are ignored.

Errors

       AuBadFlow, AuBadElement.
