public class VkPresentInfoKHR
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure describing parameters of a queue presentation.
Description

Before an application can present an image, the image's layout must be transitioned to the IMAGE_LAYOUT_PRESENT_SRC_KHR layout, or for a shared presentable image the IMAGE_LAYOUT_SHARED_PRESENT_KHR layout.

Note

When transitioning the image to IMAGE_LAYOUT_SHARED_PRESENT_KHR or IMAGE_LAYOUT_PRESENT_SRC_KHR, there is no need to delay subsequent processing, or perform any visibility operations (as QueuePresentKHR performs automatic visibility operations). To achieve this, the dstAccessMask member of the VkImageMemoryBarrier should be set to 0, and the dstStageMask parameter should be set to PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT.

Valid Usage
- Each element of pImageIndices must be the index of a presentable image acquired from the swapchain specified by the corresponding element of the pSwapchains array, and the presented image subresource must be in the IMAGE_LAYOUT_PRESENT_SRC_KHR or IMAGE_LAYOUT_SHARED_PRESENT_KHR layout at the time the operation is executed on a VkDevice
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_PRESENT_INFO_KHR
- Each pNext member of any structure (including this one) in the pNext chain must be either NULL or a pointer to a valid instance of VkDeviceGroupPresentInfoKHR, VkDisplayPresentInfoKHR, VkPresentRegionsKHR, or VkPresentTimesInfoGOOGLE
- Each sType member in the pNext chain must be unique
- If waitSemaphoreCount is not 0, pWaitSemaphores must be a valid pointer to an array of waitSemaphoreCount valid VkSemaphore handles
- pSwapchains must be a valid pointer to an array of swapchainCount valid VkSwapchainKHR handles
- pImageIndices must be a valid pointer to an array of swapchainCount uint32_t values
- If pResults is not NULL, pResults must be a valid pointer to an array of swapchainCount VkResult values
- swapchainCount must be greater than 0
- Both of the elements of pSwapchains, and the elements of pWaitSemaphores that are valid handles must have been created, allocated, or retrieved from the same VkInstance

Member documentation
- sType – the type of this structure.
- pNext – NULL or a pointer to an extension-specific structure.
- waitSemaphoreCount – the number of semaphores to wait for before issuing the present request. The number may be zero.
- pWaitSemaphores – if not NULL, is an array of VkSemaphore objects with waitSemaphoreCount entries, and specifies the semaphores to wait for before issuing the present request.
- swapchainCount – the number of swapchains being presented to by this command.
- pSwapchains – an array of VkSwapchainKHR objects with swapchainCount entries. A given swapchain must not appear in this list more than once.
- pImageIndices – an array of indices into the array of each swapchain’s presentable images, with swapchainCount entries. Each entry in this array identifies the image to present on the corresponding entry in the pSwapchains array.
- pResults – an array of VkResult typed elements with swapchainCount entries. Applications that do not need per-swapchain results can use NULL for pResults. If non-NULL, each entry in pResults will be set to the VkResult for presenting the swapchain corresponding to the same index in pSwapchains.
