Function lua_atpanic

pub fn lua_atpanic(l: LuaState, panicf: LuaCFunction) -> LuaCFunction

Sets a new panic function and returns the old one.
If an error happens outside any protected environment, Lua calls a panic function and then calls exit(EXIT_FAILURE), thus exiting the host application.
Your panic function can avoid this exit by never returning (e.g., doing a long jump).
The panic function can access the error message at the top of the stack.

Returns

The old panic function.
