LIBPERFUSE(3)              Library Functions Manual              LIBPERFUSE(3)

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

LIBRARY
     library "libperfuse"

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
     arguments:

     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
     success, 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 operation
                      throughput requires it.  Default is 2162688 bytes, which
                      is enough to queue 16 FUSE packets of maximum 132 kB
                      length.
