# VkPipelineCacheCreateFlagBits(3) Manual Page

## Name

VkPipelineCacheCreateFlagBits - Bitmask specifying the behavior of the pipeline cache

## C Specification

Possible values of the `flags` member of VkPipelineCacheCreateInfo, specifying the behavior of the pipeline cache, are:

    typedef enum VkPipelineCacheCreateFlagBits {
        VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT_EXT = 0x00000001,
        VK_PIPELINE_CACHE_CREATE_FLAG_BITS_MAX_ENUM = 0x7FFFFFFF
    } VkPipelineCacheCreateFlagBits;

## Description

- `VK_PIPELINE_CACHE_CREATE_EXTERNALLY_SYNCHRONIZED_BIT_EXT` specifies that all commands that modify the created VkPipelineCache will be externally synchronized. When set, the implementation may skip any unnecessary processing needed to support simultaneous modification from multiple threads where allowed.
