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
-
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.
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.
