C Specification

The XrNegotiateRuntimeRequest structure is defined as:

typedef struct XrNegotiateRuntimeRequest {
    XrLoaderInterfaceStructs     structType;
    uint32_t                     structVersion;
    size_t                       structSize;
    uint32_t                     runtimeInterfaceVersion;
    XrVersion                    runtimeApiVersion;
    PFN_xrGetInstanceProcAddr    getInstanceProcAddr;
} XrNegotiateRuntimeRequest;

Members

Member Descriptions

  • structType must be XR_LOADER_INTERFACE_STRUCT_RUNTIME_REQUEST.

  • structVersion must be a valid version of the structure. The value XR_RUNTIME_INFO_STRUCT_VERSION is used to describe the current version of this structure.

  • structSize must be the size in bytes of the current version of the structure (i.e. sizeof(XrNegotiateRuntimeRequest))

  • runtimeInterfaceVersion is the version of the runtime interface version being requested by the runtime. Must: not be outside of the bounds of the XrNegotiateLoaderInfo::minInterfaceVersion and XrNegotiateLoaderInfo::maxInterfaceVersion values (inclusive).

  • runtimeApiVersion is the version of the OpenXR API supported by this runtime as formatted by XR_MAKE_VERSION. Patch is ignored.

  • getInstanceProcAddr is a pointer to the runtime’s xrGetInstanceProcAddr implementation that will be used by the loader to populate a dispatch table of OpenXR functions supported by the runtime.

Description

This is an output structure from runtime negotiation. The loader must populate structType, structVersion, and structSize to ensure correct interpretation by the runtime, while the runtime populates the rest of the fields in a successful call to xrNegotiateLoaderRuntimeInterface.
