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:
// Provided by VK_KHR_display
VkResult vkGetPhysicalDeviceDisplayPropertiesKHR(
VkPhysicalDevice physicalDevice,
uint32_t* pPropertyCount,
VkDisplayPropertiesKHR* pProperties);
Parameters
-
physicalDeviceis a physical device. -
pPropertyCountis a pointer to an integer related to the number of display devices available or queried, as described below. -
pPropertiesis eitherNULLor a pointer to an array ofVkDisplayPropertiesKHRstructures.
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, and VK_INCOMPLETE will be returned instead of
VK_SUCCESS, to indicate that not all the available properties were
returned.
