void lua_cpp::push_closure	(	lua_State *	L,
		const lua_function &	f,
		int	nup
	)

Pushes a closure which retains a std::function object as its first up-value.

Note that this is NOT strictly compatible with the lua c function push_closure – if you request additional upvalues they will be indexed starting at 2 rather than 1.

Note that unlike push_function above this results in a function and not userdata being pushed on the stack.

void lua_cpp::push_function	(	lua_State *	L,
		const lua_function &	f
	)

Pushes a std::function wrapper object onto the stack.

It does not support up-values. If you need that use push_closure (a little slower).

NOTE: This object has type userdata, not function. Its metatable has a call operator. If this is not sufficient for your needs then use push_closure.

void lua_cpp::set_functions	(	lua_State *	L,
		const std::vector< lua_cpp::Reg > &	functions
	)

Analogous to lua_setfuncs, it registers a collection of function wrapper objects into a table, using push_function.

The note above applies.

void lua_cpp::set_functions	(	lua_State *	L,
		const std::vector< lua_cpp::Reg > &	functions,
		int	nup
	)

Analogous to lua_setfuncs and set_functions above, but pushes closures.

NOTE: set_functions(L, l, 0) is NOT the same as set_functions(L, l), as the latter produces userdata and the former doesn't.

void lua_cpp::set_functions	(	lua_State *	L,
