NAME

fuse_loop, fuse_loop_mt — wait for and process FUSE messages

SYNOPSIS

library “libfuse”
#include <fuse.h>

int
fuse_loop(struct fuse *fuse);

int
fuse_loop_mt(struct fuse *fuse);

DESCRIPTION

fuse_loop() reads from the FUSE device and blocks, waiting for the kernel to send it fbuf messages. Each of these specifies a FUSE file system operation to execute. The callbacks to invoke are specified by calling fuse_new(3) or fuse_setup(3) prior to calling fuse_loop().

fuse_loop() returns when it reads the FBT_DESTROY message, which indicates that the file system is being unmounted.

If FUSE signal handlers have been installed and SIGHUP, SIGINT, or SIGTERM is received, fuse_loop() terminates successfully. See fuse_set_signal_handlers(3) for more details.

fuse_loop_mt() is a multi-threaded variant that allows the file system to process multiple file system operations in parallel. This is not implemented on OpenBSD.

RETURN VALUES

fuse_loop() returns 0 on success or -1 on failure.

fuse_loop_mt() always returns -1.

SEE ALSO

fuse_main(3), fuse_set_signal_handlers(3), fb_queue(9)

STANDARDS

The fuse_loop() and fuse_loop_mt() functions conform to FUSE 2.6.

HISTORY

The fuse_loop() and fuse_loop_mt() functions first appeared in OpenBSD 5.4.
