- Subject: What is 'light' user data?

Hi Lua ML!
I'm confused about the terminology: What is 'light' user data? Is is
something special? If I write a C function which pops an (in C defined
element) from the stack and creates a copy, should I push the result
of the copy operation as light user data?
Code example:
static int config_member_copy(lua_State *L) {
struct config_member_t *mem;
struct config_member_t *copy;
mem = lua_touserdata(L, 1);
lua_pop(L, 1);
copy = some_magic_copy_function(mem);
lua_pushlightuserdata(L, copy);
return 1
}
Is this piece of code the correct approach?
