Various functions are provided for enumerating the available display devices present on a Vulkan physical device. To query information about the available displays, call:
// Provided by VK_KHR_display VkResult vkGetPhysicalDeviceDisplayPropertiesKHR( VkPhysicalDevice physicalDevice, uint32_t* pPropertyCount, VkDisplayPropertiesKHR* pProperties);
physicalDeviceis a physical device.
pPropertyCountis a pointer to an integer related to the number of display devices available or queried, as described below.
NULLor a pointer to an array of
NULL, then the number of display devices available
physicalDevice is returned in
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
If the value of
pPropertyCount is less than the number of display
physicalDevice, at most
will be written, and
VK_INCOMPLETE will be returned instead of
VK_SUCCESS, to indicate that not all the available properties were
