# VkSurfacePresentModeKHR(3) Manual Page

## Name

VkSurfacePresentModeKHR - Structure describing present mode of a surface

Loading… please wait.

## C Specification

The `VkSurfacePresentModeKHR` structure is defined as:

    // Provided by VK_KHR_surface_maintenance1
    typedef struct VkSurfacePresentModeKHR {
        VkStructureType     sType;
        void*               pNext;
        VkPresentModeKHR    presentMode;
    } VkSurfacePresentModeKHR;

or the equivalent

    // Provided by VK_EXT_surface_maintenance1
    typedef VkSurfacePresentModeKHR VkSurfacePresentModeEXT;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `presentMode` is the presentation mode the swapchain will use.

## Description

If the `VkSurfacePresentModeKHR` structure is included in the `pNext` chain of VkPhysicalDeviceSurfaceInfo2KHR, the values returned in VkSurfaceCapabilitiesKHR::`minImageCount`, VkSurfaceCapabilitiesKHR::`maxImageCount`, VkSurfacePresentScalingCapabilitiesKHR::`minScaledImageExtent`, and VkSurfacePresentScalingCapabilitiesKHR::`maxScaledImageExtent` are valid only for the specified `presentMode`. If `presentMode` is `VK_PRESENT_MODE_SHARED_DEMAND_REFRESH_KHR` or `VK_PRESENT_MODE_SHARED_CONTINUOUS_REFRESH_KHR`, the per-present mode image counts must both be one. The per-present mode image counts may be less-than or greater-than the image counts returned when `VkSurfacePresentModeKHR` is not provided.

Note | If VkSwapchainPresentModesCreateInfoKHR is provided to swapchain creation, the requirements for forward progress may be less strict. For example, a FIFO swapchain might only require 2 images to guarantee forward progress, but a MAILBOX one might require 4. Without the per-present image counts, such an implementation would have to return 4 in VkSurfaceCapabilitiesKHR::`minImageCount`, which pessimizes FIFO. Conversely, an implementation may return a low number for minImageCount, but internally bump the image count when application queries vkGetSwapchainImagesKHR, which can surprise applications, and is not discoverable until swapchain creation. Using `VkSurfacePresentModeKHR` and VkSwapchainPresentModesCreateInfoKHR together effectively removes this problem. VkSwapchainPresentModesCreateInfoKHR is required for the specification to be backwards compatible with applications that do not know about, or make use of this feature.

Valid Usage

- VUID-VkSurfacePresentModeKHR-presentMode-07780
  `presentMode` must be a value reported by vkGetPhysicalDeviceSurfacePresentModesKHR for the specified surface

Valid Usage (Implicit)

- VUID-VkSurfacePresentModeKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_SURFACE_PRESENT_MODE_KHR`

- VUID-VkSurfacePresentModeKHR-presentMode-parameter
  `presentMode` must be a valid VkPresentModeKHR value
