# VkCommandBufferUsageFlagBits(3) Manual Page

## Name

VkCommandBufferUsageFlagBits - Bitmask specifying usage behavior for command buffer

Loading… please wait.

## C Specification

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

    // Provided by VK_VERSION_1_0
    typedef enum VkCommandBufferUsageFlagBits {
        VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT = 0x00000001,
        VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT = 0x00000002,
        VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT = 0x00000004,
    } VkCommandBufferUsageFlagBits;

## Description

- `VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT` specifies that each recording of the command buffer will only be submitted once, and the command buffer will be reset and recorded again between each submission.

- `VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT` specifies that a secondary command buffer is considered to be entirely inside a render pass. If this is a primary command buffer, then this bit is ignored.

- `VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT` specifies that a command buffer can be resubmitted to any queue of the same queue family while it is in the pending state, and recorded into multiple primary command buffers.
