Overview

An XS wrapper for sd-daemon <https://www.freedesktop.org/software/systemd/man/sd-daemon.html>, the systemd daemon interface.

Exports one function, "sd_notify", by default. A variety of convenience functions are also available for import, either individually or with the ":all" tag.

For a fully featured example, see the "perl-daemon" script and "perl-daemon.service" examples in "eg".

Functions

sd_notify(@array_of_pairs)

The main function, exported by default. Takes a list of pairs and converts them to a string to be passed to the C function man:sd_notify(3) <https://www.freedesktop.org/software/systemd/man/sd_notify.html>

e.g.

  sd_notify(ready => 1, status => 'Processing requests');
