gfs_pio_seek - reposition a stream
#include <gfarm/gfarm.h> char *gfs_pio_seek (GFS_File gf, file_offset_t offset, int whence, file_offset_t * result);
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.
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.
