Name
       AuReadElement - read data from an ExportClient element in a flow

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.
