logWriterDefaultWouldDrop

Check whether funcGLib.log_writer_default and funcGLib.log_default_handler would ignore a message with the given domain and level.

As with funcGLib.log_default_handler, this function drops debug and informational messages unless their log domain (or all) is listed in the space-separated G_MESSAGES_DEBUG environment variable, or by funcGLib.log_writer_default_set_debug_domains.

This can be used when implementing log writers with the same filtering behaviour as the default, but a different destination or output format:

if (g_log_writer_default_would_drop (log_level, log_domain))
  return G_LOG_WRITER_HANDLED;
]|

or to skip an expensive computation if it is only needed for a debugging
message, and `G_MESSAGES_DEBUG` is not set:

```c
if (!g_log_writer_default_would_drop (G_LOG_LEVEL_DEBUG, G_LOG_DOMAIN))
  {
    g_autofree gchar *result = expensive_computation (my_object);

    g_debug ("my_object result: `s`", result);
  }

Params: logLevel = log level, either from glib.types.LogLevelFlags, or a user-defined level logDomain = log domain Returns: TRUE if the log message would be dropped by GLib’s default log handlers
