# VkPhysicalDeviceScalarBlockLayoutFeatures(3) Manual Page

## Name

VkPhysicalDeviceScalarBlockLayoutFeatures - Structure indicating support for scalar block layouts

## C Specification

The `VkPhysicalDeviceScalarBlockLayoutFeatures` structure is defined as:

    typedef struct VkPhysicalDeviceScalarBlockLayoutFeatures {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           scalarBlockLayout;
    } VkPhysicalDeviceScalarBlockLayoutFeatures;

or the equivalent

    typedef VkPhysicalDeviceScalarBlockLayoutFeatures VkPhysicalDeviceScalarBlockLayoutFeaturesEXT;

## Members

The members of the `VkPhysicalDeviceScalarBlockLayoutFeatures` structure describe the following features:

## Description

- `scalarBlockLayout` indicates that the implementation supports the layout of resource blocks in shaders using scalar alignment.

If the `VkPhysicalDeviceScalarBlockLayoutFeatures` structure is included in the `pNext` chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether the feature is supported. `VkPhysicalDeviceScalarBlockLayoutFeatures` can also be included in the `pNext` chain of VkDeviceCreateInfo to enable this feature.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SCALAR_BLOCK_LAYOUT_FEATURES`

## See Also

`VkBool32`, VkStructureType
