NAME
gfs_pio_seek - reposition a stream
SYNOPSIS
#include <gfarm/gfarm.h>
char *gfs_pio_seek (GFS_File gf, file_offset_t offset, int whence,
file_offset_t * result);
DESCRIPTION
The gfs_pio_seek() function sets the file position indicator for the
file gf. The new position, measured in bytes, is obtained by adding
offset bytes to the position specified by whence. If whence is set to
0, 1, or 2, the offset is relative to the start of the file, the
current position indicator, or end-of-file, respectively. When result
is not NULL, the new position returns to the address pointed by result.
RETURN VALUES
NULL The function terminated successfully.
GFARM_ERR_NO_MEMORY
Insufficient memory was available.
Others An error except the above occurred. The reason is shown by its
pointed strings.
