Hello! I often need to know return addresses in scripting. They are visible in memory viewer, but i cant find them in lua. Is there any way to get them in code?

Stackwalk isn't exposed so you'll have to read the stack yourself.

often if a function uses push rbp at the start the return will be in rbp+8. otherwise you have to inspect the function and track where the return address is in rsp
