C Specification

The xrCreateSwapchain function is defined as:

XrResult xrCreateSwapchain(
    XrSession                                   session,
    const XrSwapchainCreateInfo*                createInfo,
    XrSwapchain*                                swapchain);

Parameters

Parameter Descriptions

  • session is the session that creates the image.

  • createInfo is a pointer to an XrSwapchainCreateInfo structure containing parameters to be used to create the image.

  • swapchain is a pointer to a handle in which the created XrSwapchain is returned.

Description

Creates an XrSwapchain handle. The returned swapchain handle may be subsequently used in API calls. Multiple XrSwapchain handles may exist simultaneously, up to some limit imposed by the runtime. The XrSwapchain handle must be eventually freed via the xrDestroySwapchain function. The runtime must return XR_ERROR_SWAPCHAIN_FORMAT_UNSUPPORTED if the image format specified in the XrSwapchainCreateInfo is unsupported.
