C Specification

To create a VkSurfaceKHR object for an iOS UIView or CAMetalLayer, call:

// Provided by VK_MVK_ios_surface
VkResult vkCreateIOSSurfaceMVK(
    VkInstance                                  instance,
    const VkIOSSurfaceCreateInfoMVK*            pCreateInfo,
    const VkAllocationCallbacks*                pAllocator,
    VkSurfaceKHR*                               pSurface);

Parameters

Note

The vkCreateIOSSurfaceMVK function is considered deprecated and has been superseded by vkCreateMetalSurfaceEXT from the VK_EXT_metal_surface extension.

Description

  • instance is the instance with which to associate the surface.

  • pCreateInfo is a pointer to a VkIOSSurfaceCreateInfoMVK structure containing parameters affecting the creation of the surface object.

  • pAllocator is the allocator used for host memory allocated for the surface object when there is no more specific allocator available (see Memory Allocation).

  • pSurface is a pointer to a VkSurfaceKHR handle in which the created surface object is returned.

Valid Usage (Implicit)

  • VUID-vkCreateIOSSurfaceMVK-instance-parameter
    instance must be a valid VkInstance handle

  • VUID-vkCreateIOSSurfaceMVK-pCreateInfo-parameter
    pCreateInfo must be a valid pointer to a valid VkIOSSurfaceCreateInfoMVK structure

  • VUID-vkCreateIOSSurfaceMVK-pAllocator-parameter
    If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

  • VUID-vkCreateIOSSurfaceMVK-pSurface-parameter
    pSurface must be a valid pointer to a VkSurfaceKHR handle

Return Codes
On success, this command returns

  • VK_SUCCESS

On failure, this command returns

  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY

  • VK_ERROR_NATIVE_WINDOW_IN_USE_KHR
