vkGetPhysicalDeviceDisplayPropertiesKHR

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);

• 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.

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 application 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, and VK_INCOMPLETE will be returned instead of VK_SUCCESS, to indicate that not all the available properties were returned.
