logSetAlwaysFatal

Sets the message levels which are always fatal, in any log domain.

When a message with any of these levels is logged the program terminates. You can only set the levels defined by GLib to be fatal. flags@GLib.LogLevelFlags.LEVEL_ERROR is always fatal.

You can also make some message levels fatal at runtime by setting the G_DEBUG environment variable (see glib-running.html).

Libraries should not call this function, as it affects all messages logged by a process, including those from other libraries.

Structured log messages (using func@GLib.log_structured and func@GLib.log_structured_array) are fatal only if the default log writer is used; otherwise it is up to the writer function to determine which log messages are fatal. See logging.html#using-structured-logging.
