LIBPERFUSE(2) |
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.
