g_parse_debug_string (
  const gchar* string,
  const GDebugKey* keys,
  guint nkeys


Parses a string containing debugging options into a %guint containing bit flags. This is used within GDK and GTK to parse the debug options passed on the command line or through environment variables.

If string is equal to “all”, all flags are set. Any flags specified along with “all” in string are inverted; thus, “all,foo,bar” or “foo,bar,all” sets all flags except those corresponding to “foo” and “bar”.

If string is equal to “help”, all the available keys in keys are printed out to standard error.
