  • 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));

    Parameters

    • output_fd: number

      output file descriptor to check

    Returns boolean

    TRUE if output_fd points to the journal, FALSE otherwise
