Revision 1.13, Sun Nov 20 13:28:32 2016 UTC (7 years, 4 months ago) by pho
fuse_main(3): Support general fuse options via fuse_parse_cmdline(3) * Prototypes for fuse_new(3), fuse_mount(3), and fuse_unmount(3) now matches to the original fuse interface. * Add fuse_daemonize(3): needs to have a different prototype, otherwise we can't use puffs_daemon(3). * Remove fuse_setup(3) and fuse_teardown(3). These obsolete functions has already been removed from the original interface. * fuse_main(3) now supports the following command-line options compatible with the original fuse: -h, --help print help message -V, --version print library version (currently does nothing) -d, -o debug enable debug output (PUFFS_FLAG_OPDUMP), implies -f -f foreground mode -s single threaded mode (always enabled for now) -o fsname=NAME explicitly set the name of the file system * fuse_main(3) now daemonizes the process by default. This is for the compatibility with the original fuse. |

Operations are transported from the kernel virtual file system layer to the concrete implementation behind .Nm , where they are processed and results are sent back to the kernel. .Pp It uses the framework provided by the .Xr puffs 3 subsystem, and, through that, the kernel interface provided by .Xr puffs 4 . .Sh SEE ALSO .Xr puffs 3 , .Xr puffs 4 .Rs .%A Antti Kantee .%A Alistair Crooks .%D September 2007 .%J EuroBSDCon 2007 .%T ReFUSE: Userspace FUSE Reimplementation Using puffs .Re .Sh HISTORY An unsupported experimental version of .Nm first appeared in .Nx 5.0 . .Sh AUTHORS .An Alistair Crooks Aq Mt agc@NetBSD.org , .An Antti Kantee Aq Mt pooka@NetBSD.org .Sh BUGS Many, legion, but well-loved.
