NAME

ASetCloseDownMode − set close-down mode to destroy or complete transactions on specified connection

SYNOPSIS

#include <Alib.h> void
ASetCloseDownMode (

Audio ∗  audio,

ACloseDownMode close_mode,

long ∗  status_return );

DESCRIPTION

ASetCloseDownMode() sets the close down mode to keep or destroy active and pending transactions on the connection associated with audio. 

audio specifies the Audio structure associated with this connection. 

close_mode specifies the close-down mode.  One of the following values:

ADestroyAll − causes all active and pending transactions for this connection to be stopped and destroyed when the connection is closed; associated storage is freed immediately. 

AKeepTransactions − prevents transactions for this connection from being destroyed and allows them to complete after the close. 

status_return receives the returned status of the operation, unless this parameter is passed in as a NULL pointer.  If status_return is set to NULL, Alib will do the error handling. 

ERRORS

If status_return is not set to NULL, it can return one of the following values:

0  AENoError No error - the call completed successfully. 

2  AEBadAudio The audio structure is invalid.  A pointer to a valid audio structure may be missing (use AOpenAudio() to get a valid pointer). 

3  AEBadValue The close_mode parameter contains an incorrect value

EXAMPLE

The following example sets the close-down mode to allow transactions to complete, and sets up status to receive an error status. 

Audio ∗ audio;  /∗ audio connection ∗/

ACloseDownMode close_mode;  /∗ close down mode ∗/

long status;  /∗ error status ∗/

. 
.
.

/∗ set close down mode ∗/

close_mode = AKeepTransactions;

ASetCloseDownMode(audio, close_mode, &status);

NOTE

In order to ensure that the compiler finds the Audio Library (libAlib.sl) and the Alib.h header file, you must add the following switches:

-L /opt/audio/lib
-I/opt/audio/include

DEPENDENCIES

This function belongs to the Audio Library of functions that manage connections to an audio server.  The audio server must run on a system that has audio hardware. To find out whether or not your system has audio hardware, refer to Using the Audio Developer’s Kit or the online help for the Audio control panel.  For information about the audio capabilities of a particular system use the online example audioinfo.c.
