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.
