Re: Calling a function defined in lua from C/C++

["Turgut Hakkı ÖZDEMİR" <extronus@...>]

Greetings,

> The problem with your  example is that in your c code you are calling lua_tocfunction (look at the "c"  between "to" and "function"), which explicitly return a pointer to a C function  as Lua likes them (that is taking a lua_State* and returning an int). funk is a  pure Lua function, so lua_tocfunction returns NULL.

Hmm... where is that 'c' came from :). Sorry bothering but is there
any similar function for pure lua functions? or how can i convert them
to strings? Replacing lua_tocfunction with lua_tostring giving another
null.

Another... is it possible to get from global index (lua_getglobal)
without running the script? (And without using lua internals)

It is better if i do some goooogling isn't it? :)
