From 317181e8ea1b3406919b946ca5524f8b9f34817d Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 4 Sep 2019 15:59:18 +0100 Subject: Introduce callback for logging Introduce an API for custom log handler functions. This allows libfuse applications to send messages to syslog(3) or other logging systems. See include/fuse_log.h for details. Convert libfuse from fprintf(stderr, ...) to log_fuse(level, ...). Most messages are error messages with FUSE_LOG_ERR log level. There are also some debug messages which now use the FUSE_LOG_DEBUG log level. Note that lib/mount_util.c is used by both libfuse and fusermount3. Since fusermount3 does not link against libfuse, we cannot call fuse_log() from lib/mount_util.c. This file will continue to use fprintf(stderr, ...) until someone figures out how to split it up.
