# VkPhysicalDeviceShaderLongVectorFeaturesEXT(3) Manual Page

## Name

VkPhysicalDeviceShaderLongVectorFeaturesEXT - Structure describing long vector features that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceShaderLongVectorFeaturesEXT` structure is defined as:

    // Provided by VK_EXT_shader_long_vector
    typedef struct VkPhysicalDeviceShaderLongVectorFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           longVector;
    } VkPhysicalDeviceShaderLongVectorFeaturesEXT;

## 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.

- `longVector` indicates that the implementation supports the `LongVectorEXT` SPIR-V capability.

## Description

If the `VkPhysicalDeviceShaderLongVectorFeaturesEXT` 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 `VkPhysicalDeviceShaderLongVectorFeaturesEXT`, 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-VkPhysicalDeviceShaderLongVectorFeaturesEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_LONG_VECTOR_FEATURES_EXT

Structure Chaining
