use of jit.util.funcinfo

[zerothefallen]

Hi, I want to use jit.util.funcinfo in a script of mine to find people using cheats detouring debug.getinfo. I havent really used it and I don't really understand how it's done exactly. I see it's used as such

jit.util.funcinfo(func, pc)

I don't know pc, and I just wish to know how exactly it's used, it's args, if it's efficient to run jit on, etc

Thanks!

I assume jit needs to be on for this to work? jit.on()? or command parameters?

[no, actually]

Jit doesn't need to be on to use this. I'm not sure about the second parameter, but if you feed it a function then it'll give you back a table of information similar to debug.getinfo.
