ACloseAudio(3X)
NAME
ACloseAudio − close connection to specified audio server
SYNOPSIS
#include <Alib.h> void
ACloseAudio (
Audio ∗ audio,
long ∗ status_return );
DESCRIPTION
ACloseAudio() closes the connection to the server specified by audio and deallocates the Audio structure memory.
ACloseAudio() waits for the audio server to acknowledge that the audio connection is closed before returning. After the connection has been closed, it cannot be resumed or used in any other way.
audio specifies the Audio structure associated with this connection.
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.
17 AEOutofMemory The Audio Library attempted to allocate space but failed.
2 AEBadAudio The audio structure is invalid. A pointer to a valid audio structure may be missing (use AOpenAudio() to get a valid pointer).
EXAMPLE
The following example closes the connection to audio and sets up status to receive status data.
Audio ∗ audio; /∗ audio connection ∗/
long status; /∗ error status ∗/
.
.
.
/∗ close audio connection ∗/
ACloseAudio(audio, &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.
