Re: Different number of arguments in Lua stack in set hook function in Lua 5..4 vs Lua 5.2

Hello Francisco,

I passed ar->ftransfer in lua_getlocal() to get the returned value on the stack, but it didn't work, so I checked the indexes and values came very large.

It seems that we need to use L->ci->u2.transferinfo.ftransfer index value, not ar->ftransfer value because I'm getting the correct result, if I use  L->ci->u2.transferinfo.ftransfer.

Docs does not say they are not stack indexes, but that you use get/set
local to access them through the activation record:
https://www.lua.org/manual/5.4/manual.html#4.7

Are you using the docs or going directly to the headers defining them?
