# VkPhysicalDeviceShaderLongVectorPropertiesEXT(3) Manual Page

## Name

VkPhysicalDeviceShaderLongVectorPropertiesEXT - Structure describing long vector properties supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceShaderLongVectorPropertiesEXT` structure is defined as:

    // Provided by VK_EXT_shader_long_vector
    typedef struct VkPhysicalDeviceShaderLongVectorPropertiesEXT {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           maxVectorComponents;
    } VkPhysicalDeviceShaderLongVectorPropertiesEXT;

## Members

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

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

- `maxVectorComponents` indicates the maximum number of components that can be in a vector type.

## Description

If the `VkPhysicalDeviceShaderLongVectorPropertiesEXT` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceShaderLongVectorPropertiesEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_LONG_VECTOR_PROPERTIES_EXT

Structure Chaining

Extends the structure

  - VkPhysicalDeviceProperties2
