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.
