VkFreeFunctionI (LWJGL 3.3.1 - Vulkan)

All Superinterfaces:

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

All Known Implementing Classes:

VkFreeFunction

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 VkFreeFunctionI
extends org.lwjgl.system.CallbackI
```
Application-defined memory free function.
C Specification

The type of pfnFree is:
```
 typedef void (VKAPI_PTR *PFN_vkFreeFunction)(
     void*                                       pUserData,
     void*                                       pMemory);
```
Description

pMemory may be NULL, which the callback must handle safely. If pMemory is non-NULL, it must be a pointer previously allocated by pfnAllocation or pfnReallocation. The application should free this memory.
