DESCRIPTION
gfs_pio_open() opens a file in the Gfarm file system specified by gfarm_url , and returns a GFS_File structure to the address pointed by gfp . gfarm_url is a path name in the Gfarm file system, or a Gfarm URL in the form of gfarm://metaserver:port/path/name.
Values of flags are constructed by a bitwise-inclusive-OR of the following list. Exactly one of the first three values should be specified:
GFARM_FILE_RDONLY
Open for reading only.
GFARM_FILE_WRONLY
Open for writing only.
GFARM_FILE_RDWR

GFARM_ERR_TOO_MANY_OPEN_FILES
The process opens too many files.
GFARM_ERR_TOO_MANY_OPEN_FILES_IN_SYSTEM
