My problem is I didn't get an error. I got a ton of blank lines. The file has 4.5k of lines. I'm not sure what the preferred method is to deal with huge files.

AFGETFRAMECOUNT(3)														AFGETFRAMECOUNT(3)

NAME

       afGetFrameCount, afGetTrackBytes, afGetDataOffset - get the total sample frame count, length of audio track in bytes, offset of the audio
       track for a track in an audio file

SYNOPSIS

       #include <audiofile.h>

       AFframecount afGetFrameCount (AFfilehandle file, int track);

       AFfileoffset afGetTrackBytes (AFfilehandle file, int track);

       AFfileoffset afGetDataOffset (AFfilehandle file, int track);

PARAMETERS

       file is an audio file handle created by a previous call to afOpenFile(3).

       track is an integer which specifies an audio track within file. All supported file formats contain exactly one audio track per file, so the
       constant AF_DEFAULT_TRACK should always be used.

DESCRIPTION

       afGetFrameCount returns the total number of sample frames contained within the specified track of the specified file.

       Each sample frame of audio consists of a fixed number of samples (equal to the number of audio channels in the track. For monaural data, a
       sample frame consists of one audio sample. For stereophonic data, a sample frame consists of a stereo pair.

       afGetTrackBytes returns the total number of bytes of raw audio data (i.e., prior to decompression or conversion) in the track.

       afGetDataOffset returns the offset in bytes of the start of the audio data contained within the specified track of the specified file.

RETURN VALUE

       afGetFrameCount returns the total number of sample frames in track.

       afGetTrackBytes returns the total number of bytes of audio data in track.

       afGetDataOffset returns the offset in bytes to the beginning of the audio data in track.

       Each of these routines returns -1 in case of error.
