- 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/systemd/plain/src/systemd/sd-daemon.h
- http://cgit.freedesktop.org/systemd/systemd/plain/src/libsystemd-daemon/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.
-
- See sd-daemon(3) for more information.

- 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"
-
- WATCHDOG=1 Tells systemd to update the watchdog timestamp.
- Services using this feature should do this in
- regular intervals. A watchdog framework can use the
- timestamps to detect failed services.
-
- 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");
-
- See sd_notifyf() for more complete examples.

- "MAINPID=%lu",

-
- Example 2: A daemon could send the following shortly before
- exiting, on failure:

- sd_notifyf(0, "STATUS=Failed to start up: %s\n"
