Structure hint of rectangular regions changed by vkQueuePresentKHR.
Valid Usage
- swapchainCount must be the same value as VkPresentInfoKHR::swapchainCount, where VkPresentInfoKHR is in the pNext chain of this VkPresentRegionsKHR structure
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_PRESENT_REGIONS_KHR
- If pRegions is not NULL, pRegions must be a valid pointer to an array of swapchainCount valid VkPresentRegionKHR structures
- swapchainCount must be greater than 0

- sType – the type of this structure.
- pNext – NULL or a pointer to an extension-specific structure.
- swapchainCount – the number of swapchains being presented to by this command.
- pRegions – NULL or a pointer to an array of VkPresentRegionKHR elements with swapchainCount entries. If not NULL, each element of pRegions contains the region that has changed since the last present to the swapchain in the corresponding entry in the VkPresentInfoKHR::pSwapchains array.
