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:

// Provided by VK_KHR_external_memory_win32
VkResult vkGetMemoryWin32HandlePropertiesKHR(
    VkDevice                                    device,
    VkExternalMemoryHandleTypeFlagBits          handleType,
    HANDLE                                      handle,
    VkMemoryWin32HandlePropertiesKHR*           pMemoryWin32HandleProperties);


  • device is the logical device that will be importing handle.

  • handleType is the type of the handle handle.

  • handle is the handle which will be imported.

  • pMemoryWin32HandleProperties will return properties of handle.


Valid Usage
  • handle must be an external memory handle created outside of the Vulkan API

  • handleType must not be one of the handle types defined as opaque

Valid Usage (Implicit)
Return Codes
On success, this command returns

On failure, this command returns
