# VkCommandPoolCreateFlagBits(3) Manual Page

## Name

VkCommandPoolCreateFlagBits - Bitmask specifying usage behavior for a command pool

Loading… please wait.

## C Specification

Bits which can be set in VkCommandPoolCreateInfo::`flags`, specifying usage behavior for a command pool, are:

    // Provided by VK_VERSION_1_0
    typedef enum VkCommandPoolCreateFlagBits {
        VK_COMMAND_POOL_CREATE_TRANSIENT_BIT = 0x00000001,
        VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT = 0x00000002,
      // Provided by VK_VERSION_1_1
        VK_COMMAND_POOL_CREATE_PROTECTED_BIT = 0x00000004,
    } VkCommandPoolCreateFlagBits;

## Description

- `VK_COMMAND_POOL_CREATE_TRANSIENT_BIT` specifies that command buffers allocated from the pool will be short-lived, meaning that they will be reset or freed in a relatively short timeframe. This flag may be used by the implementation to control memory allocation behavior within the pool.

- `VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT` allows any command buffer allocated from a pool to be individually reset to the initial state; either by calling vkResetCommandBuffer, or via the implicit reset when calling vkBeginCommandBuffer. If this flag is not set on a pool, then `vkResetCommandBuffer` must not be called for any command buffer allocated from that pool.

- `VK_COMMAND_POOL_CREATE_PROTECTED_BIT` specifies that command buffers allocated from the pool are protected command buffers.
