lua_xmove between non related lua_State's

[Mark_Swinhoe@...]

Hi all,

I'm using lua 5.1.1 and in the documentation
it says:

void lua_xmove (lua_State *from, lua_State *to, int
n);
Exchange values between different threads of the same
global state. 
This function pops n
values from the stack from,
and pushes them onto the stack to.

link: http://www.lua.org/manual/5.1/manual.html#lua_xmove

However I've tried it out with unrelated lua_State's and it seems to work fine. I'm guessing when it says 'same global state' its referring to coroutines or using lua_newthread. Could someone clarify if I'm allowed to do this as its extremely useful.

Thanks,

Mark Swinhoe
