VkDebugUtilsMessengerCallbackEXT (LWJGL 3.2.3 - Vulkan)

java.lang.Object
- org.lwjgl.system.Callback
- - org.lwjgl.vulkan.VkDebugUtilsMessengerCallbackEXT

All Implemented Interfaces:

java.lang.AutoCloseable, org.lwjgl.system.CallbackI, org.lwjgl.system.CallbackI.I, org.lwjgl.system.NativeResource, org.lwjgl.system.Pointer, VkDebugUtilsMessengerCallbackEXTI
```
public abstract class VkDebugUtilsMessengerCallbackEXT
extends org.lwjgl.system.Callback
implements VkDebugUtilsMessengerCallbackEXTI
```
Application-defined debug messenger callback function.
C Specification

The prototype for the VkDebugUtilsMessengerCreateInfoEXT::pfnUserCallback function implemented by the application is:
```
 typedef VkBool32 (VKAPI_PTR *PFN_vkDebugUtilsMessengerCallbackEXT)(
     VkDebugUtilsMessageSeverityFlagBitsEXT           messageSeverity,
     VkDebugUtilsMessageTypeFlagsEXT                  messageTypes,
     const VkDebugUtilsMessengerCallbackDataEXT*      pCallbackData,
     void*                                            pUserData);
```
Description

The callback must not call DestroyDebugUtilsMessengerEXT.

The callback returns a VkBool32, which is interpreted in a layer-specified manner. The application should always return FALSE. The TRUE value is reserved for use in layer development.
