C Specification

To query Vulkan API version requirements, call:

// Provided by XR_KHR_vulkan_enable
XrResult xrGetVulkanGraphicsRequirementsKHR(
    XrInstance                                  instance,
    XrSystemId                                  systemId,
    XrGraphicsRequirementsVulkanKHR*            graphicsRequirements);

Parameters
