## C Specification

Values which may be returned in the `rayTracingInvocationReorderReorderingHint` field of `VkPhysicalDeviceRayTracingInvocationReorderPropertiesEXT` or `VkPhysicalDeviceRayTracingInvocationReorderPropertiesNV` are:

    // Provided by VK_EXT_ray_tracing_invocation_reorder
    typedef enum VkRayTracingInvocationReorderModeEXT {
        VK_RAY_TRACING_INVOCATION_REORDER_MODE_NONE_EXT = 0,
        VK_RAY_TRACING_INVOCATION_REORDER_MODE_REORDER_EXT = 1,
      // Provided by VK_NV_ray_tracing_invocation_reorder
        VK_RAY_TRACING_INVOCATION_REORDER_MODE_NONE_NV = VK_RAY_TRACING_INVOCATION_REORDER_MODE_NONE_EXT,
      // Provided by VK_NV_ray_tracing_invocation_reorder
        VK_RAY_TRACING_INVOCATION_REORDER_MODE_REORDER_NV = VK_RAY_TRACING_INVOCATION_REORDER_MODE_REORDER_EXT,
    } VkRayTracingInvocationReorderModeEXT;

    // Provided by VK_NV_ray_tracing_invocation_reorder
    // Equivalent to VkRayTracingInvocationReorderModeEXT
    typedef VkRayTracingInvocationReorderModeEXT VkRayTracingInvocationReorderModeNV;

## Description

- `VK_RAY_TRACING_INVOCATION_REORDER_MODE_NONE_EXT` specifies that the implementation does not reorder at reorder calls.

- `VK_RAY_TRACING_INVOCATION_REORDER_MODE_REORDER_EXT` specifies that the implementation may reorder at reorder calls.
