NAME

       gfs_pio_create - create a file in the Gfarm file system

SYNOPSIS

       #include <gfarm/gfarm.h>

       gfarm_error_t gfs_pio_create (const char * gfarm_url, int flags, gfarm_mode_t mode, GFS_File * gfp);

DESCRIPTION

       gfs_pio_create()  creates  a  new file in the Gfarm file system whose name is the string pointed to by gfarm_url with the access mode mode,
       and returns a GFS_File structure to the address pointed to by gfp.  Mode specifies the file permissions to be created, and is  modified	by
       the process's umask.

       The  flags  argument  has  the  same  meaning  as  the  second  argument  of  gfs_pio_open(),  including the point such that exactly one of
       GFARM_FILE_RDONLY, GFARM_FILE_WRONLY, and GFARM_FILE_RDWR should be specified.

       Note that GFARM_FILE_TRUNC must be explicitly specified by the flags argument if needed.
