FUSE_LOOP(3) Library Functions Manual FUSE_LOOP(3)

fuse_loop, fuse_loop_mtwait for and process FUSE messages

#include <fuse.h>

int
fuse_loop(struct fuse *fuse);

int
fuse_loop_mt(struct fuse *fuse);

() 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().

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

If FUSE signaler handlers have been installed and either SIGHUP, SIGINT or SIGTERM is received then () will attempt to unmount the file system. See fuse_set_signal_handlers(3).

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

fuse_loop() will return 0 on success and -1 on failure.

fuse_loop_mt() always returns -1.

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

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

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