Function Prototype
vkRegisterDisplayEventEXT
Signal a fence when a display event occurs
To create a fence that will be signaled when an event occurs on a VkDisplayKHR object, call:
VkResult vkRegisterDisplayEventEXT(
VkDevice device,
VkDisplayKHR display,
const VkDisplayEventInfoEXT* pDisplayEventInfo,
const VkAllocationCallbacks* pAllocator,
VkFence* pFence);
device
is a logical device associated withdisplay
display
is the display on which the event may occur.pDisplayEventInfo
is a pointer to a VkDisplayEventInfoEXT structure describing the event of interest to the application.pAllocator
controls host memory allocation as described in the Memory Allocation chapter.pFence
is a pointer to a handle in which the resulting fence object is returned.
Valid Usage (Implicit)
VUID-vkRegisterDisplayEventEXT-device-parameter
device
must be a valid VkDevice handle
VUID-vkRegisterDisplayEventEXT-display-parameter
display
must be a valid VkDisplayKHR handle
VUID-vkRegisterDisplayEventEXT-pDisplayEventInfo-parameter
pDisplayEventInfo
must be a valid pointer to a valid VkDisplayEventInfoEXT structure
VUID-vkRegisterDisplayEventEXT-pAllocator-parameter
If pAllocator
is not NULL
, pAllocator
must be a valid pointer to a valid VkAllocationCallbacks structure
VUID-vkRegisterDisplayEventEXT-pFence-parameter
pFence
