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.
