Function enable_hook

pub fn enable_hook(original: *const ()) -> Result<(), Error>

Enables a previously added hook, replacing the original function with the new one.

Errors

This function returns a retour::Error if:

• Enabling the hook fails.

Example

use commonlibsse_ng::skse::trampoline::{add_hook, remove_hook, enable_hook};
use retour::Error;

fn add5(val: i32) -> i32 {
    val + 5
}

fn add10(val: i32) -> i32 {
    val + 10
}

let original = add5 as *const ();
let replacement = add10 as *const ();

// Initially, the behavior is to add 5
assert_eq!(add5(5), 10);

// Add a hook to replace `add5` with `add10`
unsafe { add_hook(original, replacement) }.unwrap();
assert_eq!(add5(5), 15);

assert!(enable_hook(original).is_ok());
assert_eq!(add5(5), 15);
