This extension enables an application to export Windows handles from Vulkan memory objects and to import Vulkan memory objects from Windows handles exported from other Vulkan memory objects or from similar resources in other APIs.

     * Get a Windows HANDLE for a memory object.
     * 
     * C Specification
     * 
     * To export a Windows handle representing the underlying resources of a Vulkan device memory object, call:
     * 
     *      * VkResult vkGetMemoryWin32HandleKHR(
     *     VkDevice                                    device,

     * 
     * Description
     * 
     * For handle types defined as NT handles, the handles returned by {@link #vkGetMemoryWin32HandleKHR GetMemoryWin32HandleKHR} are owned by the application. To avoid leaking resources, the application must release ownership of them using the {@code CloseHandle} system call when they are no longer needed.
     * 
     * Valid Usage (Implicit)
     * 
     * 
     * {@code device} must be a valid {@code VkDevice} handle
     * {@code pGetWin32HandleInfo} must be a valid pointer to a valid {@link VkMemoryGetWin32HandleInfoKHR} structure
     * {@code pHandle} must be a valid pointer to a {@code HANDLE} value
     * 
     * 
     * Return Codes
     * 
     * 
     * On success, this command returns
     * 
     * {@link VK10#VK_SUCCESS SUCCESS}
     * 
     * On failure, this command returns
     * 
     * {@link VK10#VK_ERROR_TOO_MANY_OBJECTS ERROR_TOO_MANY_OBJECTS}

     * @param pHandle             will return the Windows handle representing the underlying resources of the device memory object.

     * Get Properties of External Memory Win32 Handles.
     * 
     * C Specification
     * 
     * Windows memory handles compatible with Vulkan may also be created by non-Vulkan APIs using methods beyond the scope of this specification. To determine the correct parameters to use when importing such handles, call:

     * 
     * Valid Usage
     * 
     * 
     * {@code handle} must be an external memory handle created outside of the Vulkan API.
     * {@code handleType} must not be one of the handle types defined as opaque.
     *

     * Valid Usage (Implicit)
     * 
     * 
     * {@code device} must be a valid {@code VkDevice} handle
