C Specification
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);
Parameters
-
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. -
pDisplaysis eitherNULLor a pointer to an array ofVkDisplayKHRhandles.
Description
If pDisplays is NULL, then the number of displays usable with the
specified planeIndex for physicalDevice is returned in
pDisplayCount.
Otherwise, pDisplayCount must point to a variable set by the
application to the number of elements in the pDisplays array, and on
return the variable is overwritten with the number of handles actually
written to pDisplays.
If the value of pDisplayCount is less than the number of usable
display-plane pairs for physicalDevice, at most pDisplayCount
handles will be written, and VK_INCOMPLETE will be returned instead of
VK_SUCCESS, to indicate that not all the available pairs were
returned.
