LogFunc
Specifies the prototype of log handler functions.
The default log handler, g_log_default_handler(), automatically appends a new-line character to @message when printing it. It is advised that any custom log handler functions behave similarly, so that logging calls in user code do not need modifying to add a new-line character to the message if the log handler is changed.
This is not used if structured logging is enabled; see using-structured-logging.
