afInitAESChannelDataTo(3)
=========================
NAME
----
afInitAESChannelDataTo, afInitAESChannelData - initialize AES non-audio
data in an audio file setup
SYNOPSIS
--------
#include <audiofile.h>
void afInitAESChannelDataTo(AFfilesetup setup, int track, int willHaveData);
void afInitAESChannelData(AFfilesetup setup, int track);
PARAMETERS
----------
`setup` is a valid file setup returned by linkaf:afNewFileSetup[3].
`track` specifies a track within the audio file setup. `track` is always
`AF_DEFAULT_TRACK` for all currently supported file formats.
`willHaveData` is a boolean-valued integer indicating whether AES
non-audio data will be present.
DESCRIPTION
-----------
Given an `AFfilesetup` structure created with linkaf:afNewFileSetup[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.
Currently only AIFF and AIFF-C file formats can store AES non-audio data;
this data is ignored in all other file formats.
ERRORS
------
`afInitAESChannelDataTo` and `afInitAESChannelData` can produce the
following errors:
`AF_BAD_FILESETUP`:: `setup` represents an invalid file setup.
`AF_BAD_TRACKID`:: `track` represents an invalid track identifier.
