LIBSYSTEMD(3) libsystemd LIBSYSTEMD(3)
libsystemd - Functions for implementing services and interacting
with systemd

The libsystemd library provides functions that allow interacting
with various interfaces provided by the systemd(1) service
manager, as well as various other functions and constants useful
for implementing services in general.
See sd-bus(3), sd-bus-errors(3), sd-daemon(3), sd-device(3),
sd-event(3), sd-hwdb(3), sd-id128(3), sd-journal(3), sd-json(3),
and sd-login(3) for information about different parts of the
library interface.
Strict backwards-compatibility is maintained for the API
(application programming interface) and ABI (application binary
interface). Symbol versioning is used, with symbols only added
and never removed.
Functions described here are available as a shared library, which
can be compiled against and linked to with the
libsystemd pkg-config(1) file.
The code described here uses getenv(3), which is declared to be
not multi-thread-safe. This means that the code calling the
functions described here must not call setenv(3) from a parallel
thread. It is recommended to only do calls to setenv() from an
early phase of the program when no other threads have been
started.
