VkPhysicalDevicePrimitiveRestartIndexFeaturesEXT(3)

# VkPhysicalDevicePrimitiveRestartIndexFeaturesEXT(3) Manual Page

## Name

VkPhysicalDevicePrimitiveRestartIndexFeaturesEXT - Structure describing features to configure primitive restart index

## C Specification

The `VkPhysicalDevicePrimitiveRestartIndexFeaturesEXT` structure is defined as:

    // Provided by VK_EXT_primitive_restart_index
    typedef struct VkPhysicalDevicePrimitiveRestartIndexFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           primitiveRestartIndex;
    } VkPhysicalDevicePrimitiveRestartIndexFeaturesEXT;

## Members

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

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

- `primitiveRestartIndex` specifies whether the index for primitive restart can be set

## Description

If the `VkPhysicalDevicePrimitiveRestartIndexFeaturesEXT` 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 `VkPhysicalDevicePrimitiveRestartIndexFeaturesEXT`, 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-VkPhysicalDevicePrimitiveRestartIndexFeaturesEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_PRIMITIVE_RESTART_INDEX_FEATURES_EXT

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo

  - VkPhysicalDeviceFeatures2
