## Name

VkPerformanceStreamMarkerInfoINTEL - Structure specifying stream performance markers

Loading… please wait.

## C Specification

The `VkPerformanceStreamMarkerInfoINTEL` structure is defined as:

    // Provided by VK_INTEL_performance_query
    typedef struct VkPerformanceStreamMarkerInfoINTEL {
        VkStructureType    sType;
        const void*        pNext;
        uint32_t           marker;
    } VkPerformanceStreamMarkerInfoINTEL;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `marker` is the marker value that will be recorded into the reports consumed by an external application.

## Description

Valid Usage

- VUID-VkPerformanceStreamMarkerInfoINTEL-marker-02735
  The value written by the application into `marker` must only used the valid bits as reported by vkGetPerformanceParameterINTEL with the `VK_PERFORMANCE_PARAMETER_TYPE_STREAM_MARKER_VALID_BITS_INTEL`

Valid Usage (Implicit)

- VUID-VkPerformanceStreamMarkerInfoINTEL-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PERFORMANCE_STREAM_MARKER_INFO_INTEL`

- VUID-VkPerformanceStreamMarkerInfoINTEL-pNext-pNext
  `pNext` must be `NULL`
