LIBPERFUSE(3) FreeBSD 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.
