## Name

vkGetMemoryWin32HandlePropertiesKHR - Get Properties of External Memory Win32 Handles

Loading… please wait.

## 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);

## Parameters

- `device` is the logical device that will be importing `handle`.

- `handleType` is a VkExternalMemoryHandleTypeFlagBits value specifying the type of the handle `handle`.

- `handle` is the handle which will be imported.

- `pMemoryWin32HandleProperties` is a pointer to a VkMemoryWin32HandlePropertiesKHR structure in which properties of `handle` are returned.

## Description

Valid Usage

- VUID-vkGetMemoryWin32HandlePropertiesKHR-handle-00665
  `handle` must point to a valid Windows memory handle

- VUID-vkGetMemoryWin32HandlePropertiesKHR-handleType-00666
  `handleType` must not be one of the handle types defined as opaque

Valid Usage (Implicit)

- VUID-vkGetMemoryWin32HandlePropertiesKHR-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkGetMemoryWin32HandlePropertiesKHR-handleType-parameter
  `handleType` must be a valid VkExternalMemoryHandleTypeFlagBits value

- VUID-vkGetMemoryWin32HandlePropertiesKHR-pMemoryWin32HandleProperties-parameter
  `pMemoryWin32HandleProperties` must be a valid pointer to a VkMemoryWin32HandlePropertiesKHR structure

Return Codes

On success, this command returns

  - VK_SUCCESS

On failure, this command returns

  - VK_ERROR_INVALID_EXTERNAL_HANDLE

  - VK_ERROR_OUT_OF_HOST_MEMORY

  - VK_ERROR_UNKNOWN

  - VK_ERROR_VALIDATION_FAILED
