AFSEEKFRAME(3)AFSEEKFRAME(3)NAME
afSeekFrame, afTellFrame - update or access the current sample frame position for a track in an audio file
SYNOPSIS
#include <audiofile.h>
AFframecount afSeekFrame(AFfilehandle file, int track,
AFframecount frameOffset);
AFframecount afTellFrame(AFfilehandle file, int track);
PARAMETERS
file is a valid audio file handle created by afOpenFile(3).
track identifies an audio track within the file. track is always AF_DEFAULT_TRACK for all currently supported audio file formats.
frameOffset is a sample frame offset. Valid sample frame offsets must be greater than or equal to zero and strictly less than the number of
sample frames contained within the specified audio track. The special value -1 is also allowed.
DESCRIPTION
afSeekFrame moves the logical file position for a specified audio track to a desired sample frame location. If frameOffset is -1,
afSeekFrame will not modify the current file offset and will instead return the current file position.
afTellFrame returns current file position in sample frames.
RETURN VALUE
On success, afSeekFrame and afTellFrame will return the current file position as measured in sample frames from the start of the audio
track. On failure, afSeekFrame and afTellFrame will return the value -1.
ERRORS
The following errors can be generated by afSeekFrame or afTellFrame:
AF_BAD_FILEHANDLE
file does not represent a valid file handle.
AF_BAD_TRACK
track does not identify a valid track.
AF_BAD_LSEEK
A call to lseek failed.

SYNOPSIS
#include <audiofile.h>
AFframecount afWriteFrames(AFfilehandle file, int track, const void *data,
AFframecount count);
DESCRIPTION
afWriteFrames attempts to write up to count frames of audio data from the buffer data to the audio file handle file.
PARAMETERS
file is a valid file handle returned by afOpenFile(3).
track is always AF_DEFAULT_TRACK for all currently supported file formats.
data is a buffer of sample frames to be written to the file.
count is the number of sample frames to be written.
RETURN VALUE
afWriteFrames returns the number of sample frames successfully written to file.
ERRORS
afWriteFrames can produce these errors:
AF_BAD_FILEHANDLE
the file handle was invalid
AF_BAD_TRACKID
the track is not AF_DEFAULT_TRACK
AF_BAD_WRITE
writing audio data to the file failed
AF_BAD_LSEEK
seeking within the file failed
