LIBPERFUSE(3)           NetBSD Library Functions Manual          LIBPERFUSE(3)


NAME

     perfuse_mount, perfuse_open -- Request a puffs(3) mount from perfused(8)


LIBRARY

     PUFFS-enabled Relay to FUSE Library (libperfuse, -lperfuse)


SYNOPSIS

     #include <perfuse.h>

     int
     perfuse_mount(const char *source, const char *dir,
         const char *filesystemtype, long int mountflags, void *data);

     int
     perfuse_open(const char *path, int flags);


DESCRIPTION

     perfuse_mount() sends a mount request to perfused(8).  It is intended as
     a drop-in replacement for mount(2) for FUSE file systems daemons and
     libraries, so that they can work with perfused(8).

     The function prototype mimics Linux's mount(2), with the following argu-
     ments:

     source  The source file system that will appear in df(1) and mount(8)
             listings.  Defaults to /dev/fuse if NULL.

     dir     The file system mount point.

     filesystemtype
             The file system type, as displayed by df(1) and mount(8).
             Defaults to ``fuse'' if NULL.

     mountflags
             This contains the same value as a mount(2) flags argument.

     data    This contains the same value as a mount(2) data argument.

     perfuse_open() is a drop-in replacement for the open(2) system call where
     /dev/fuse is used.  If path is different than /dev/fuse, perfuse_open()
     handles control to the regular open(2).


RETURN VALUES

     perfuse_mount() returns a file descriptor to the /dev/fuse socket on suc-
     cess, and causes exit on failure.


ENVIRONMENT

     PERFUSE_OPTIONS    Comma-separated values controlling the usage of some
                        FUSE methods.  Allowed values are enable_access,
                        disable_access, enable_creat, disable_creat.

     PERFUSE_BUFSIZE    Set the socket buffer sizes used for communication
                        with the filesystem.  This should be raised as opera-
                        tion throughput requires it.  Default is 2162688
                        bytes, which is enough to queue 16 FUSE packets of
                        maximum 132 kB length.
