PID file management for daemons.
pid-file crate wraps the
pidfile family of functions provided by BSD
systems that provide mutual exclusion for daemons via PID files.
Much of the code is inherited from pidfile_rs, but the build system bundles the necessary subset of libbsd rather than relying on libbsd to be installed.
- An open PID file.
- pidfh 🔒
