Notes
- This function is provided by the reference
- implementation of APIs for new-style daemons and
- distributed with the systemd package. The algorithm it
- implements is simple, and can easily be reimplemented
- in daemons if it is important to support this
- interface without using the reference
- implementation.
+ These APIs are implemented as a shared library,
+ which can be compiled and linked to with the
+ libsystemd pkg-config1
+ file.
Internally, this function checks whether the
- /sys/fs/cgroup/systemd virtual file
- system is mounted, by comparing the st_dev value of
- the stat() data of
- /sys/fs/cgroup and
- /sys/fs/cgroup/systemd.
-
- For details about the algorithm check the
- liberally licensed reference implementation sources:

- resp.
-
- sd_booted() is 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. For more details about the reference
- implementation see
- sd_daemon7.
-
- If the reference implementation is used as
- drop-in files and -DDISABLE_SYSTEMD is set during
- compilation this function will always return 0 and
- otherwise become a NOP.
