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.
