C Specification

To complete recording of a command buffer, call:

// Provided by VK_VERSION_1_0
VkResult vkEndCommandBuffer(
    VkCommandBuffer                             commandBuffer);

Parameters

  • commandBuffer is the command buffer to complete recording.

Description

The command buffer must have been in the recording state, and, if successful, is moved to the executable state.

If there was an error during recording, the application will be notified by an unsuccessful return code returned by vkEndCommandBuffer, and the command buffer will be moved to the invalid state.

If recording a command would exceed the amount of command pool memory reserved by VkCommandPoolMemoryReservationCreateInfo::commandPoolReservedSize or the maximum supported command buffer size reported in VkPhysicalDeviceVulkanSC10Properties::maxCommandBufferSize, the implementation may report a VK_FAULT_TYPE_COMMAND_BUFFER_FULL fault. The command buffer remains in the recording state until vkEndCommandBuffer is called. When vkEndCommandBuffer is called on a command buffer for which the command pool memory reservation was exceeded during recording, it must return VK_ERROR_OUT_OF_DEVICE_MEMORY.

If VkPhysicalDeviceVulkanSC10Properties::deviceNoDynamicHostAllocations is VK_TRUE, vkEndCommandBuffer must not return VK_ERROR_OUT_OF_HOST_MEMORY.

Valid Usage

  • VUID-vkEndCommandBuffer-commandBuffer-00059
    commandBuffer must be in the recording state

  • VUID-vkEndCommandBuffer-commandBuffer-00060
    If commandBuffer is a primary command buffer, there must not be an active render pass instance

  • VUID-vkEndCommandBuffer-commandBuffer-00061
    All queries made active during the recording of commandBuffer must have been made inactive

  • VUID-vkEndCommandBuffer-commandBuffer-01815
    If commandBuffer is a secondary command buffer, there must not be an outstanding vkCmdBeginDebugUtilsLabelEXT command recorded to commandBuffer that has not previously been ended by a call to vkCmdEndDebugUtilsLabelEXT

Valid Usage (Implicit)

  • VUID-vkEndCommandBuffer-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

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_DEVICE_MEMORY

  • VK_ERROR_OUT_OF_HOST_MEMORY

  • VK_ERROR_UNKNOWN

  • VK_ERROR_VALIDATION_FAILED
