NAME

AAudioString − get name of audio server (string) passed to AOpenAudio()

SYNOPSIS

#include <Alib.h> char ∗
AAudioString (

Audio ∗  audio );

DESCRIPTION

audio specifies the Audio structure associated with this connection. 

RETURN VALUE

Upon successful completion, AAudioString() returns the server_name (string) that was passed to AOpenAudio().  If server_name was NULL, the value could identify the AUDIO or DISPLAY environment variable or the name of the local host (see man page for AOpenAudio()). 

ERRORS

AAudioString() does not return an error status.  Note that the application program may crash if audio does not point to a valid Audio structure. 

EXAMPLE

The following call to AAudioString() gets the name of the audio server (string) that was passed to AOpenAudio(). 

char ∗ server_name;  /∗ name of audio server∗/

Audio ∗ audio;  /∗ audio connection ∗/
.
.
.

/∗ get audio server name and print it∗/

server_name = AAudioString(audio);
printf("audio server string is %s",server_name);

NOTES

AAudioString() is a convenience function that enables the client program to examine a component of the internal Audio structure that is created by AOpenAudio().  The contents of the structure should be treated as read-only. 

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.
