VkCommandBufferUsageFlagBits(3)

# VkCommandBufferUsageFlagBits(3) Manual Page

## Name

VkCommandBufferUsageFlagBits - Bitmask specifying usage behavior for command buffer

## C Specification

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

    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,
        VK_COMMAND_BUFFER_USAGE_FLAG_BITS_MAX_ENUM = 0x7FFFFFFF
    } 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 a queue while it is in the pending state, and recorded into multiple primary command buffers.
