C Specification

To query information about the available displays, call:

// Provided by VK_KHR_get_display_properties2
VkResult vkGetPhysicalDeviceDisplayProperties2KHR(
    VkPhysicalDevice                            physicalDevice,
    uint32_t*                                   pPropertyCount,
    VkDisplayProperties2KHR*                    pProperties);

Parameters

  • physicalDevice is a physical device.

  • pPropertyCount is a pointer to an integer related to the number of display devices available or queried, as described below.

  • pProperties is either NULL or a pointer to an array of VkDisplayProperties2KHR structures.

Description

vkGetPhysicalDeviceDisplayProperties2KHR behaves similarly to vkGetPhysicalDeviceDisplayPropertiesKHR, with the ability to return extended information via chained output structures.

If VkPhysicalDeviceVulkanSC10Properties::deviceNoDynamicHostAllocations is VK_TRUE, vkGetPhysicalDeviceDisplayProperties2KHR must not return VK_ERROR_OUT_OF_HOST_MEMORY.

Valid Usage (Implicit)

  • VUID-vkGetPhysicalDeviceDisplayProperties2KHR-physicalDevice-parameter
    physicalDevice must be a valid VkPhysicalDevice handle

  • VUID-vkGetPhysicalDeviceDisplayProperties2KHR-pPropertyCount-parameter
    pPropertyCount must be a valid pointer to a uint32_t value

  • VUID-vkGetPhysicalDeviceDisplayProperties2KHR-pProperties-parameter
    If the value referenced by pPropertyCount is not 0, and pProperties is not NULL, pProperties must be a valid pointer to an array of pPropertyCount VkDisplayProperties2KHR structures

Return Codes
On success, this command returns

  • VK_SUCCESS

  • VK_INCOMPLETE

On failure, this command returns

  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY
