-+ Reference implementation of a few systemd related interfaces for
-+ writing daemons. These interfaces are trivial to implement. To
-+ simplify porting we provide this reference implementation.
-+ Applications are welcome to reimplement the algorithms described
-+ here if they do not want to include these two source files.
-+
-+ The following functionality is provided:
-+
-+ - Support for logging with log levels on stderr
-+ - File descriptor passing for socket-based activation
-+ - Daemon startup and status notification
-+ - Detection of systemd boots
-+
-+ You may compile this with -DDISABLE_SYSTEMD to disable systemd
-+ support. This makes all those calls NOPs that are directly related to
-+ systemd (i.e. only sd_is_xxx() will stay useful).
-+
-+ Since this is drop-in code we don't want any of our symbols to be
-+ exported in any case. Hence we declare hidden visibility for all of
-+ them.
-+
-+ You may find an up-to-date version of these source files online:
-+
-+ http://cgit.freedesktop.org/systemd/plain/src/sd-daemon.h
-+ http://cgit.freedesktop.org/systemd/plain/src/sd-daemon.c
-+
-+ This should compile on non-Linux systems, too, but with the
-+ exception of the sd_is_xxx() calls all functions will become NOPs.

-+ Informs systemd about changed daemon state. This takes a number of
-+ newline separated environment-style variable assignments in a
-+ string. The following variables are known:
-+
-+ READY=1 Tells systemd that daemon startup is finished (only
-+ relevant for services of Type=notify). The passed
-+ argument is a boolean "1" or "0". Since there is
-+ little value in signaling non-readiness the only
-+ value daemons should send is "READY=1".
-+
-+ STATUS=... Passes a single-line status string back to systemd
-+ that describes the daemon state. This is free-from
-+ and can be used for various purposes: general state
-+ feedback, fsck-like programs could pass completion
-+ percentages and failing programs could pass a human
-+ readable error message. Example: "STATUS=Completed
-+ 66% of file system check..."
-+
-+ ERRNO=... If a daemon fails, the errno-style error code,
-+ formatted as string. Example: "ERRNO=2" for ENOENT.
-+
-+ BUSERROR=... If a daemon fails, the D-Bus error-style error
-+ code. Example: "BUSERROR=org.freedesktop.DBus.Error.TimedOut"
-+
-+ MAINPID=... The main pid of a daemon, in case systemd did not
-+ fork off the process itself. Example: "MAINPID=4711"
-+
-+ Daemons can choose to send additional variables. However, it is
-+ recommended to prefix variable names not listed above with X_.
-+
-+ Returns a negative errno-style error code on failure. Returns > 0
-+ if systemd could be notified, 0 if it couldn't possibly because
-+ systemd is not running.
-+
-+ Example: When a daemon finished starting up, it could issue this
-+ call to notify systemd about it:

-+ sd_notify(0, "READY=1");
