Re: Existence of a luabind::execute_file function ?

Just want to make sure before starting and after consulting the pil (
http://www.lua.org/pil/25.2.html) and this page :
http://www.corsix.org/content/common-lua-pitfall-loading-code, I should push
the error handler function on the stack before loading file ( since loading
file basically embeds the file into a function and pushes it onto the
stack). Only then can I call pcall ?

So in lua:
-push error handler
-load file
-lua_pcall(L, 0,LUA_MULTRET, lua_gettop(L)-1)  ?

I could also use luabind::detail::pcall(L,1,0) so that the error handler is
"lua_inserted" under the loaded file chunk ?


Nb: Just to be sure is answer http://www.luafaq.org/#T7.6 correct ? it looks
correct to me but as it is an unofficial FAQ...
