VkMemoryBarrierAccessFlags3KHR(3)

# VkMemoryBarrierAccessFlags3KHR(3) Manual Page

## Name

VkMemoryBarrierAccessFlags3KHR - Structure specifying additional access flags

## C Specification

The `VkMemoryBarrierAccessFlags3KHR` structure is defined as:

    // Provided by VK_KHR_maintenance8
    typedef struct VkMemoryBarrierAccessFlags3KHR {
        VkStructureType      sType;
        const void*          pNext;
        VkAccessFlags3KHR    srcAccessMask3;
        VkAccessFlags3KHR    dstAccessMask3;
    } VkMemoryBarrierAccessFlags3KHR;

## Members

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

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

- `srcAccessMask3` is a VkAccessFlags3KHR mask of access flags to be included in the first access scope.

- `dstAccessMask3` is a VkAccessFlags3KHR mask of access flags to be included in the second access scope.

## Description

Valid Usage (Implicit)

- VUID-VkMemoryBarrierAccessFlags3KHR-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_MEMORY_BARRIER_ACCESS_FLAGS_3_KHR

- VUID-VkMemoryBarrierAccessFlags3KHR-srcAccessMask3-parameter
  `srcAccessMask3` must be a valid combination of VkAccessFlagBits3KHR values

- VUID-VkMemoryBarrierAccessFlags3KHR-dstAccessMask3-parameter
  `dstAccessMask3` must be a valid combination of VkAccessFlagBits3KHR values
