`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.
