            GNOME_VFS_OPEN_NONE = 0,
            GNOME_VFS_OPEN_READ = 1 << 0,
            GNOME_VFS_OPEN_WRITE = 1 << 1,
            GNOME_VFS_OPEN_RANDOM = 1 << 2,
    	GNOME_VFS_OPEN_TRUNCATE = 1 << 3
    } GnomeVFSOpenMode;

Mode in which files are opened. If GNOME_VFS_OPEN_RANDOM is not used, the file will be have to be accessed sequentially.

Move a file from URI `old_uri` to `new_uri`. This will only work if `old_uri` and `new_uri` are on the same file system. Otherwise, it is necessary to use the more general %`gnome_vfs_xfer_uri()` function.

`old_uri` : | Source URI

`source` : | A URI
`target` : | Another URI
`same_fs_return` : | Pointer to a boolean variable which will be set to `TRUE`
