.SH "NAME"
afInitAESChannelDataTo, afInitAESChannelData \- initialize AES non\-audio data in an audio file setup
.SH "SYNOPSIS"
.sp
.nf
#include <audiofile\&.h>
.fi
.sp
.nf
void afInitAESChannelDataTo(AFfilesetup setup, int track, int willHaveData);
void afInitAESChannelData(AFfilesetup setup, int track);
.fi
.SH "PARAMETERS"
.sp
setup is a valid file setup returned by \fBafNewFileSetup\fR(3)\&.
.sp
track specifies a track within the audio file setup\&. track is always AF_DEFAULT_TRACK for all currently supported file formats\&.
.sp
willHaveData is a boolean\-valued integer indicating whether AES non\-audio data will be present\&.
.SH "DESCRIPTION"
.sp
Given an AFfilesetup structure created with \fBafNewFileSetup\fR(3) and a track identified by track (AF_DEFAULT_TRACK for all currently supported file formats), afInitAESChannelDataTo initializes the track to contain or not contain AES non\-audio data\&. afInitAESChannelData behaves similarly but always initializes the track to contain AES non\-audio data\&.
.sp
Currently only AIFF and AIFF\-C file formats can store AES non\-audio data; this data is ignored in all other file formats\&.
.SH "ERRORS"
.sp
afInitAESChannelDataTo and afInitAESChannelData can produce the following errors:
.PP
AF_BAD_FILESETUP
.RS 4
setup
represents an invalid file setup\&.
.RE
.PP
AF_BAD_TRACKID
.RS 4
track
represents an invalid track identifier\&.
.RE
