oth

Read the coroutine that made the intercepted call from inside an OTH callback. Use it when callback diagnostics need to identify the caller.

Get the original function bridge from inside an OTH callback. Call it when you need to bypass every installed hook layer.

Add a hook layer to a C closure. Its optional filter selects which calls reach this layer; misses continue to earlier layers or the original.

Report whether the current coroutine is running an OTH callback. Use it to distinguish callback work from ordinary script work.

Remove one OTH hook layer from a target. Select a specific layer when several callbacks have been installed.
