C Specification

To begin recording a command buffer, call:

// Provided by VK_VERSION_1_0
VkResult vkBeginCommandBuffer(
    VkCommandBuffer                             commandBuffer,
    const VkCommandBufferBeginInfo*             pBeginInfo);

Parameters

  • commandBuffer is the handle of the command buffer which is to be put in the recording state.

  • pBeginInfo points to a VkCommandBufferBeginInfo structure defining additional information about how the command buffer begins recording.

Description

Valid Usage
  • VUID-vkBeginCommandBuffer-commandBuffer-00049
    commandBuffer must not be in the recording or pending state

  • VUID-vkBeginCommandBuffer-commandBuffer-00050
    If commandBuffer was allocated from a VkCommandPool which did not have the VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT flag set, commandBuffer must be in the initial state

  • VUID-vkBeginCommandBuffer-commandBuffer-00051
    If commandBuffer is a secondary command buffer, the pInheritanceInfo member of pBeginInfo must be a valid VkCommandBufferInheritanceInfo structure

  • VUID-vkBeginCommandBuffer-commandBuffer-00052
    If commandBuffer is a secondary command buffer and either the occlusionQueryEnable member of the pInheritanceInfo member of pBeginInfo is VK_FALSE, or the precise occlusion queries feature is not enabled, the queryFlags member of the pInheritanceInfo member pBeginInfo must not contain VK_QUERY_CONTROL_PRECISE_BIT

  • VUID-vkBeginCommandBuffer-commandBuffer-02840
    If commandBuffer is a primary command buffer, then pBeginInfo->flags must not set both the VK_COMMAND_BUFFER_USAGE_ONE_TIME_SUBMIT_BIT and the VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT flags

Valid Usage (Implicit)
  • VUID-vkBeginCommandBuffer-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkBeginCommandBuffer-pBeginInfo-parameter
    pBeginInfo must be a valid pointer to a valid VkCommandBufferBeginInfo structure

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

  • Host access to the VkCommandPool that commandBuffer was allocated from must be externally synchronized

Return Codes
On success, this command returns
  • VK_SUCCESS

On failure, this command returns
  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_OUT_OF_DEVICE_MEMORY
