logWriterIsJournald
Check whether the given @output_fd file descriptor is a connection to the systemd journal, or something else (like a log file or stdout or stderr).
Invalid file descriptors are accepted and return false, which allows for the following construct without needing any additional error handling: | is_journald = g_log_writer_is_journald (fileno (stderr)); |
Return
true if @output_fd points to the journal, false otherwise
