- Notes
-
- These interfaces are provided by the reference
- implementation of APIs for new-style daemons and
- distributed with the systemd package. The algorithms
- they implement are simple, and can easily be
- reimplemented in daemons if it is important to support
- this interface without using the reference
- implementation. See the respective function man pages
- for details.

- In addition, for details about the algorithms

-
- These APIs are implemented in the reference
- implementation's sd-daemon.c and
- sd-daemon.h files. These
- interfaces are available as shared library, which can
- be compiled and linked to with the
- libsystemd-daemon
- pkg-config1
- file. Alternatively, applications consuming these APIs
- may copy the implementation into their source tree,
- either verbatim or in excerpts.
-
- The functions directly related to new-style
- daemons become NOPs when -DDISABLE_SYSTEMD is set
- during compilation and the reference implementation is
- used as drop-in files. In addition, if
- sd-daemon.c is compiled on
- non-Linux systems they become NOPs.
