 *
 * @param obj A handle to an Edje object
 * @param emission The signal's "emission" string
 * @param source The signal's "source" string
 * @param func The callback function to be executed when the signal is
 * emitted.
 * @param data A pointer to data to pass in to @p func.
 *
 * Edje signals are one of the communication interfaces between
 * @b code and a given Edje object's @b theme. With signals, one can
 * communicate two string values at a time, which are:
 * - "emission" value: the name of the signal, in general
 * - "source" value: a name for the signal's context, in general
 *
 * Though there are those common uses for the two strings, one is free
 * to use them however they like.
 *
 * This function adds a callback function to a signal emitted by @a obj, to
 * be issued every time an EDC program like the following
 * @code
 * program {
 *   name: "emit_example";
 *   action: SIGNAL_EMIT "a_signal" "a_source";
 * }
 * @endcode
 * is run, if @p emission and @p source are given those same values,
 * here.
 *
 * Signal callback registration is powerful, in the way that @b blobs
 * may be used to match <b>multiple signals at once</b>. All the @c
 * "*?[\" set of @c fnmatch() operators can be used, both for @p
 * emission and @p source.
 *
 * Edje has @b internal signals it will emit, automatically, on
 * various actions taking place on group parts. For example, the mouse
 * cursor being moved, pressed, released, etc., over a given part's
 * area, all generate individual signals.
 *
 * By using something like
 * @code
 * edje_object_signal_callback_add(obj, "mouse,down,*", "button.*",
 *                                 signal_cb, NULL);
 * @endcode
 * being @c "button.*" the pattern for the names of parts implementing
 * buttons on an interface, you'd be registering for notifications on
 * events of mouse buttons being pressed down on either of those parts
 * (those events all have the @c "mouse,down," common prefix on their
 * names, with a suffix giving the button number). The actual emission
 * and source strings of an event will be passed in as the @a emission
 * and @a source parameters of the callback function (e.g. @c
 * "mouse,down,2" and @c "button.close"), for each of those events.
 *
 * @note See @ref edcref "the syntax" for EDC files
