afInitAESChannelDataTo, afInitAESChannelData - initialize AES non-audio data in an audio file setup
#include <audiofile.h>
void afInitAESChannelDataTo(AFfilesetup setup, int track, int willHaveData); void afInitAESChannelData(AFfilesetup setup, int track);
setup is a valid file setup returned by 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.
Given an AFfilesetup structure created with 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.
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.
