# VkPhysicalDeviceRawAccessChainsFeaturesNV(3) Manual Page

## Name

VkPhysicalDeviceRawAccessChainsFeaturesNV - Structure describing shader raw access chains features that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceRawAccessChainsFeaturesNV` structure is defined as:

    // Provided by VK_NV_raw_access_chains
    typedef struct VkPhysicalDeviceRawAccessChainsFeaturesNV {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shaderRawAccessChains;
    } VkPhysicalDeviceRawAccessChainsFeaturesNV;

## Members

This structure describes the following feature:

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

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

- `shaderRawAccessChains` specifies whether shader modules can declare the `RawAccessChainsNV` capability.

## Description

If the `VkPhysicalDeviceRawAccessChainsFeaturesNV` 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 `VkPhysicalDeviceRawAccessChainsFeaturesNV`, 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-VkPhysicalDeviceRawAccessChainsFeaturesNV-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_RAW_ACCESS_CHAINS_FEATURES_NV
