# VkPhysicalDevicePrimitivesGeneratedQueryFeaturesEXT(3) Manual Page

## Name

VkPhysicalDevicePrimitivesGeneratedQueryFeaturesEXT - Structure describing support for primitives generated query

Loading… please wait.

## C Specification

The `VkPhysicalDevicePrimitivesGeneratedQueryFeaturesEXT` structure is defined as:

    // Provided by VK_EXT_primitives_generated_query
    typedef struct VkPhysicalDevicePrimitivesGeneratedQueryFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           primitivesGeneratedQuery;
        VkBool32           primitivesGeneratedQueryWithRasterizerDiscard;
        VkBool32           primitivesGeneratedQueryWithNonZeroStreams;
    } VkPhysicalDevicePrimitivesGeneratedQueryFeaturesEXT;

## Members

This structure describes the following features:

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

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

- `primitivesGeneratedQuery` indicates whether the implementation supports the `VK_QUERY_TYPE_PRIMITIVES_GENERATED_EXT` query type.

- `primitivesGeneratedQueryWithRasterizerDiscard` indicates whether the implementation supports this query when rasterization discard is enabled.

- `primitivesGeneratedQueryWithNonZeroStreams` indicates whether the implementation supports this query with a non-zero index in vkCmdBeginQueryIndexedEXT.

## Description

If the `VkPhysicalDevicePrimitivesGeneratedQueryFeaturesEXT` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by `VkPhysicalDevicePrimitivesGeneratedQueryFeaturesEXT`, it must add an instance of the structure, with the desired feature members set to `VK_TRUE`, to the `pNext` chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

- VUID-VkPhysicalDevicePrimitivesGeneratedQueryFeaturesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PRIMITIVES_GENERATED_QUERY_FEATURES_EXT`
