/**
 * Application-defined memory free function.
 * 
 * C Specification
 * 
 * The type of {@code pfnFree} is:
 * 
 * typedef void (VKAPI_PTR *PFN_vkFreeFunction)(
    void*                                       pUserData,
    void*                                       pMemory);
 * 
 * Description
 * 
 * {@code pMemory} may be {@code NULL}, which the callback must handle safely. If {@code pMemory} is non-{@code NULL}, it must be a pointer previously allocated by {@code pfnAllocation} or {@code pfnReallocation}. The application should free this memory.
 * 
 * See Also
 * 
 * {@link VkAllocationCallbacks}
