C Specification

The createFlags are a combination of the following:

// Flag bits for XrSwapchainCreateFlags
static const XrSwapchainCreateFlags XR_SWAPCHAIN_CREATE_PROTECTED_CONTENT_BIT = 0x00000001;
static const XrSwapchainCreateFlags XR_SWAPCHAIN_CREATE_STATIC_IMAGE_BIT = 0x00000002;

Description

Flag Descriptions

  • XR_SWAPCHAIN_CREATE_PROTECTED_CONTENT_BIT indicates that the swapchain’s images will be protected from CPU access, using a mechanism such as Vulkan protected memory.

  • XR_SWAPCHAIN_CREATE_STATIC_IMAGE_BIT indicates that the application will acquire and release only one image to this swapchain over its entire lifetime. When this flag is present, runtimes should allocate fewer images than for regular swapchains to reduce memory use.

A runtime may implement any of these, but is not required to.
