C Specification

Each display has one or more supported modes associated with it by default. These built-in modes are queried by calling:

// Provided by VK_KHR_display
VkResult vkGetDisplayModePropertiesKHR(
    VkPhysicalDevice                            physicalDevice,
    VkDisplayKHR                                display,
    uint32_t*                                   pPropertyCount,
    VkDisplayModePropertiesKHR*                 pProperties);

Parameters

  • physicalDevice is the physical device associated with display.

  • display is the display to query.

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

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

Description

If pProperties is NULL, then the number of display modes available on the specified display for physicalDevice is returned in pPropertyCount. Otherwise, pPropertyCount must point to a variable set by the user to the number of elements in the pProperties array, and on return the variable is overwritten with the number of structures actually written to pProperties. If the value of pPropertyCount is less than the number of display modes for physicalDevice, at most pPropertyCount structures will be written, and VK_INCOMPLETE will be returned instead of VK_SUCCESS, to indicate that not all the available display modes were returned.

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

Valid Usage (Implicit)

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

  • VUID-vkGetDisplayModePropertiesKHR-display-parameter
    display must be a valid VkDisplayKHR handle

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

  • VUID-vkGetDisplayModePropertiesKHR-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 VkDisplayModePropertiesKHR structures

  • VUID-vkGetDisplayModePropertiesKHR-display-parent
    display must have been created, allocated, or retrieved from physicalDevice

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
