## C Specification

// Provided by VK_EXT_shader_image_atomic_int64
VkStructureType    sType;
void*              pNext;
VkBool32           sparseImageInt64Atomics;
} VkPhysicalDeviceShaderImageAtomicInt64FeaturesEXT;

## Members

This structure describes the following features:

## Description

• sType is the type of this structure.

• pNext is NULL or a pointer to a structure extending this structure.

• shaderImageInt64Atomics indicates whether shaders can support 64-bit unsigned and signed integer atomic operations on images.

• sparseImageInt64Atomics indicates whether 64-bit integer atomics can be used on sparse images.

If the VkPhysicalDeviceShaderAtomicInt64FeaturesEXT 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. VkPhysicalDeviceShaderAtomicInt64FeaturesEXT can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)
sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_IMAGE_ATOMIC_INT64_FEATURES_EXT
