# VkPhysicalDeviceFragmentShaderInterlockFeaturesEXT(3) Manual Page

## Name

VkPhysicalDeviceFragmentShaderInterlockFeaturesEXT - Structure describing fragment shader interlock features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceFragmentShaderInterlockFeaturesEXT` structure is defined as:

    typedef struct VkPhysicalDeviceFragmentShaderInterlockFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           fragmentShaderSampleInterlock;
        VkBool32           fragmentShaderPixelInterlock;
        VkBool32           fragmentShaderShadingRateInterlock;
    } VkPhysicalDeviceFragmentShaderInterlockFeaturesEXT;

## Members

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

## Description

- `fragmentShaderSampleInterlock` indicates that the implementation supports the `FragmentShaderSampleInterlockEXT` SPIR-V capability.

- `fragmentShaderPixelInterlock` indicates that the implementation supports the `FragmentShaderPixelInterlockEXT` SPIR-V capability.

- `fragmentShaderShadingRateInterlock` indicates that the implementation supports the `FragmentShaderShadingRateInterlockEXT` SPIR-V capability.

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

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FRAGMENT_SHADER_INTERLOCK_FEATURES_EXT`
