# VkSwapchainCreateFlagBitsKHR(3) Manual Page

## Name

VkSwapchainCreateFlagBitsKHR - Bitmask controlling swapchain creation

## C Specification

Bits which can be set in VkSwapchainCreateInfoKHR::`flags`, specifying parameters of swapchain creation, are:

    typedef enum VkSwapchainCreateFlagBitsKHR {
        VK_SWAPCHAIN_CREATE_SPLIT_INSTANCE_BIND_REGIONS_BIT_KHR = 0x00000001,
        VK_SWAPCHAIN_CREATE_PROTECTED_BIT_KHR = 0x00000002,
        VK_SWAPCHAIN_CREATE_MUTABLE_FORMAT_BIT_KHR = 0x00000004,
        VK_SWAPCHAIN_CREATE_FLAG_BITS_MAX_ENUM_KHR = 0x7FFFFFFF
    } VkSwapchainCreateFlagBitsKHR;

## Description

- `VK_SWAPCHAIN_CREATE_SPLIT_INSTANCE_BIND_REGIONS_BIT_KHR` specifies that images created from the swapchain (i.e. with the `swapchain` member of VkImageSwapchainCreateInfoKHR set to this swapchain’s handle) must use `VK_IMAGE_CREATE_SPLIT_INSTANCE_BIND_REGIONS_BIT`.

- `VK_SWAPCHAIN_CREATE_PROTECTED_BIT_KHR` specifies that images created from the swapchain are protected images.

- `VK_SWAPCHAIN_CREATE_MUTABLE_FORMAT_BIT_KHR` specifies that the images of the swapchain can be used to create a `VkImageView` with a different format than what the swapchain was created with. The list of allowed image view formats are specified by adding a VkImageFormatListCreateInfo structure to the `pNext` chain of `VkSwapchainCreateInfoKHR`. In addition, this flag also specifies that the swapchain can be created with usage flags that are not supported for the format the swapchain is created with but are supported for at least one of the allowed image view formats.
