SDL_HintCallback (LibSDL4J 2.24.2-1.0 API)

All Superinterfaces:

com.sun.jna.Callback

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface SDL_HintCallback
extends com.sun.jna.Callback
```
Warning: It is necessary to keep a reference to the callback object somewhere in your Java program, otherwise JNA would dispose of the object (GC would clean it) and the callback function would no longer be available for SDL library's C code to call.

In case you did not keep the reference you would encounter an error like this:

JNA: callback object has been garbage collected
