Interface VkDebugUtilsMessengerCallbackEXTI

All Superinterfaces:

org.lwjgl.system.CallbackI, org.lwjgl.system.CallbackI.I, org.lwjgl.system.Pointer

All Known Implementing Classes:

VkDebugUtilsMessengerCallbackEXT

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 VkDebugUtilsMessengerCallbackEXTI
extends org.lwjgl.system.CallbackI.I

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.
