# VkDependencyFlagBits(3) Manual Page

## Name

VkDependencyFlagBits - Bitmask specifying how execution and memory dependencies are formed

## C Specification

Bits which can be set in `vkCmdPipelineBarrier`::`dependencyFlags`, specifying how execution and memory dependencies are formed, are:

    typedef enum VkDependencyFlagBits {
        VK_DEPENDENCY_BY_REGION_BIT = 0x00000001,
        VK_DEPENDENCY_DEVICE_GROUP_BIT = 0x00000004,
        VK_DEPENDENCY_VIEW_LOCAL_BIT = 0x00000002,
        VK_DEPENDENCY_VIEW_LOCAL_BIT_KHR = VK_DEPENDENCY_VIEW_LOCAL_BIT,
        VK_DEPENDENCY_DEVICE_GROUP_BIT_KHR = VK_DEPENDENCY_DEVICE_GROUP_BIT,
        VK_DEPENDENCY_FLAG_BITS_MAX_ENUM = 0x7FFFFFFF
    } VkDependencyFlagBits;

## Description

- `VK_DEPENDENCY_BY_REGION_BIT` specifies that dependencies will be framebuffer-local.

- `VK_DEPENDENCY_VIEW_LOCAL_BIT` specifies that a subpass has more than one view.

- `VK_DEPENDENCY_DEVICE_GROUP_BIT` specifies that dependencies are non-device-local dependency.
