Summary0000220: wrong lua symhandler for local
Descriptionfollowing code is working fine (when ce attached to target process):
but following code will produce error: "Error:Failure determining what MessageBoxA means"

I think add symhandler to ce it self is a good choice, with that user even can combine autoassambler & lua function to register a new lua native function at runtime from inside ce, or manipulate directly with winapi function. eg: you donot provide "getCurrentLuaState" function but user can hocking ce's lua_pcall to get CE's luaState with serveral assembly line instead writing a dll plugin to do that.

Add errorOnLookupFailure(false) in front of your script so getAddress returns nil

Not sure what you mean with the other part
You can already add symbols to the symbolhandler in ce using "registerSymbol(symbolname, address, OPTIONAL donotsave)"
Auto assembler can read lua global functions using the $ sign in front of the name
e.g. Let's say you have the lua variable bla with the address of something, then you can do mov eax,$bla to set eax to the variable of bla. (Only valid when the script is executed, doesn't update afterwards)

uh, no, i mean the function showMessage(getAddress("MessageBoxA",true)) always failed. here is my code. the purpose is get lua_pcall address.
--method 1:
dd lua_pcall
--method 2:

the method 1 worked fine, whatever i'm set errorOnLookupFailure to true or false, but method 2 wont work, i through you are using same function to lookup lua_pcall, but it seem you don't, so method 2 don't work.
and for other part, i saw you want export bit-wise operator to ce (in main.lua in svn), i just think about add it through lua-script & assembler to export real lua_cfunction to lua script, but i'm used svn so the method 1 won't worked.
