gfs_pio_set_view_local - change file view to the corresponding fragment
char *gfs_pio_set_view_local (GFS_File gf, int flags);
gfs_pio_set_view_local() changes the process’s view of the data in the
file specified by gf to a file fragment in the local file view. The
local file view model assumes each process has its own file fragment
which is specified by the argument node of gfs_pio_set_local(3).
The total number of file fragments is also specified by the argument
nnode of gfs_pio_set_local(3). If it is different from the total
fragment number of the existent file, it is erroneous.
Before changing to the local file view, it is necessary to call
gfs_pio_set_local(3) in advance.
Values of flag are constructed by a bitwise-inclusive-OR of
GFARM_FILE_SEQUENTIAL, GFARM_FILE_REPLICATE, and
GFARM_FILE_NOT_REPLICATE. For details, refer to
By default, Gfarm files are accessed as a whole file in global file
