RE: How to get Lua functions address?

[Benoit Germain <bgermain@...>]

this should do the trick ?


// get the handleKey function
lua_pushliteral ( L , "handleKey" ) ;
lua_getglobal ( L , -1 ) ;
// push whatever argument that describes the key
...
// and call the function
lua_call(L,1,0);


or, if you don't want to intern the function name each time, do this once:

lua_pushliteral ( L , "handleKey" ) ;
lua_getglobal ( L , -1 ) ;
someVar = lua_ref ( L , true ) ;

and then you can just:


// get the handleKey function
lua_getref ( L , someVar ) ;
// push whatever argument that describes the key
...
// and call the function
lua_call(L,1,0);



Cheers,


Benoit.

Sorry, but I don´t understand!

All I need is to store a reference/point to a lua function
and call it when I need!

For example

In setkey.lua


function handleKey(key)
.
.
.
end

-- My C function
SetKeyFunction(handleKey)

In setkey.c, I must store the address of handleKey, and 
call it when the user press a key...


The answer is: How SetFunctionKey gets the reference/address
of handleKey???

Thanks for any tip!
