get_selection_count

Gets the number of accessible children currently selected.

Note: callers should not rely on null or on a zero value for indication of whether AtkSelectionIface is implemented, they should use type checking/interface checking macros or the atk_get_accessible_value convenience method.

Parameters:

this	a Object instance that implements AtkSelectionIface

Returns:

a gint representing the number of items selected, or 0 if this does not implement this interface.
