VKGETPHYSICALDEVICED(3)

NAME
vkGetPhysicalDeviceDisplayPropertiesKHR - Query information about the available displays

C SPECIFICATION

Various functions are provided for enumerating the available display devices present on a Vulkan physical device. To query information about the available displays, call:

    VkResult vkGetPhysicalDeviceDisplayPropertiesKHR(
        VkPhysicalDevice                            physicalDevice,
        uint32_t*                                   pPropertyCount,
        VkDisplayPropertiesKHR*                     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 VkDisplayPropertiesKHR structures.

DESCRIPTION

If pProperties is NULL, then the number of display devices available 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 devices for physicalDevice, at most pPropertyCount structures will be written. If pPropertyCount is smaller than the number of display devices available for physicalDevice, VK_INCOMPLETE will be returned instead of VK_SUCCESS to indicate that not all the available values were returned.

VALID USAGE

    • physicalDevice must be a valid VkPhysicalDevice handle

    • pPropertyCount must be a pointer to a uint32_t value

    • If the value referenced by pPropertyCount is not 0, and pProperties is not NULL, pProperties must be a pointer to an array of pPropertyCount VkDisplayPropertiesKHR 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
