Typedef Documentation

typedef void(* PurplePrefCallback)(const char *name, PurplePrefType type, gconstpointer val, gpointer data)

The type of callbacks for preference changes.

Parameters:
name the name of the preference which has changed.
type the type of the preferenced named name
val the new value of the preferencs; should be cast to the correct type. For instance, to recover the value of a PURPLE_PREF_INT preference, use GPOINTER_TO_INT(val). Alternatively, just call purple_prefs_get_int(), purple_prefs_get_string_list() etc.
data Arbitrary data specified when the callback was connected with purple_prefs_connect_callback().
