GLib-2.0 ▶ GLib ▶ log_get_always_fatalSince 2.86

Gets the current fatal mask.

This is mostly used by custom log writers to make fatal messages (fatal-warnings, fatal-criticals) work as expected, when using the G_DEBUG environment variable (see Running GLib Applications).

An example usage is shown below:

static GLogWriterOutput
my_custom_log_writer_fn (GLogLevelFlags log_level,
                         const GLogField *fields,
                         gsize n_fields,
                         gpointer user_data)
{

   // abort if the message was fatal
   if (log_level & g_log_get_always_fatal ())
     g_abort ();

   // custom log handling code
   ...
   ...

   // success
   return G_LOG_WRITER_HANDLED;
}
