To determine which displays a plane is usable with, call
// Provided by VK_KHR_display VkResult vkGetDisplayPlaneSupportedDisplaysKHR( VkPhysicalDevice physicalDevice, uint32_t planeIndex, uint32_t* pDisplayCount, VkDisplayKHR* pDisplays);
physicalDeviceis a physical device.
planeIndexis the plane which the application wishes to use, and must be in the range [0, physical device plane count - 1].
pDisplayCountis a pointer to an integer related to the number of displays available or queried, as described below.
NULLor a pointer to an array of
NULL, then the number of displays usable with the
physicalDevice is returned in
pDisplayCount must point to a variable set by the user to
the number of elements in the
pDisplays array, and on return the
variable is overwritten with the number of handles actually written to
If the value of
pDisplayCount is less than the number of usable
display-plane pairs for
physicalDevice, at most
handles will be written, and
VK_INCOMPLETE will be returned instead of
VK_SUCCESS, to indicate that not all the available pairs were
