ASimpleRecorder(3X)
NAME
ASimpleRecorder − return gain matrix of basic recording device
SYNOPSIS
#include <Alib.h> AGainMatrix ∗
ASimpleRecorder (
Audio ∗ audio );
DESCRIPTION
audio specifies the Audio structure associated with this connection.
RETURN VALUE
Upon succesful completion, ASimpleRecorder() returns a gain matrix of the basic audio recording device supported by the audio controller associated with the connection specified by audio.
ERRORS
ASimpleRecorder() does not return an error status.
EXAMPLE
The following example gets the gain matrix of the basic audio recording device supported by the audio controller associated with the connection specified by audio.
AGainMatrix ∗ srmatrix; /∗ simple record gain matrix ∗/
Audio ∗ audio; /∗ audio connection ∗/
.
.
.
/∗ get the simple record gain matrix ∗/
srmatrix = ASimpleRecorder(audio);
NOTES
ASimpleRecorder() 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.
