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);
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.
pPropertyCount is smaller than the number of display devices
VK_INCOMPLETE will be returned
VK_SUCCESS to indicate that not all the available values
