sd_pid_get_session() may be
used to determine the login session identifier of a
- process identified by the specified process identifier. The session
- identifier is a short string (up to 64 characters),
- consisting only of the characters a-zA-Z0-9 as well as
- '-' and '_'. It is suitable for usage in file system
- paths. Note that not all processes are part of a login
- session (e.g. system service processes and user
- processes that are shared between multiple sessions of
- the same user). For processes not being part of a
- login session this function will fail. The returned
- string needs to be freed with the libc
