vkGetSwapchainImagesKHR

To obtain the array of presentable images associated with a swapchain, call:

VkResult vkGetSwapchainImagesKHR(
    VkDevice device,
    VkSwapchainKHR swapchain,
    uint32_t* pSwapchainImageCount,
    VkImage* pSwapchainImages);

• device is the device associated with swapchain.
• swapchain is the swapchain to query.
• pSwapchainImageCount is a pointer to an integer related to the number of presentable images available or queried, as described below.
• pSwapchainImages is either NULL or a pointer to an array of VkImage handles.

If pSwapchainImages is NULL, then the number of presentable images for swapchain is returned in pSwapchainImageCount. Otherwise, pSwapchainImageCount must point to a variable set by the application to the number of elements in the pSwapchainImages array, and on return the variable is overwritten with the number of structures actually written to pSwapchainImages. If the value of pSwapchainImageCount is less than the number of presentable images for swapchain, at most pSwapchainImageCount structures will be written, and VK_INCOMPLETE will be returned instead of VK_SUCCESS, to indicate that not all the available presentable images were returned.
