Object Hierarchy:

Description:

[ CCode ( copy_function = "g_value_copy" , destroy_function = "g_value_unset" , get_value_function = "g_value_get_boxed" , marshaller_type_name = "BOXED" , set_value_function = "g_value_set_boxed" , take_value_function = "g_value_take_boxed" , type_id = "G_TYPE_VALUE" , type_signature = "v" ) ]
public struct Value

Example: GLib.Value and strings:

public static int main (string[] args) {
	Value value1 = Value (typeof (string));
	value1.set_string ("My string");

	// Output: ``My string``
	print ("%s\n", value1.get_string ());

	// Output: ``My string``
	print ("%s\n", value1.dup_string ());

	// Output: ``My string``
	print ("%s\n", (string) value1);

	// Output: ``My string 2``
	value1 = "My string 2";
	print ("%s\n", (string) value1);

	return 0;
}
