C Specification

Secondary command buffers must not be directly submitted to a queue. To record a secondary command buffer to execute as part of a primary command buffer, call:

// Provided by VK_VERSION_1_0
void vkCmdExecuteCommands(
    VkCommandBuffer                             commandBuffer,
    uint32_t                                    commandBufferCount,
    const VkCommandBuffer*                      pCommandBuffers);

Parameters

  • commandBuffer is a handle to a primary command buffer that the secondary command buffers are executed in.

  • commandBufferCount is the length of the pCommandBuffers array.

  • pCommandBuffers is a pointer to an array of commandBufferCount secondary command buffer handles, which are recorded to execute in the primary command buffer in the order they are listed in the array.

Description

If any element of pCommandBuffers was not recorded with the VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT flag, and it was recorded into any other primary command buffer which is currently in the executable or recording state, that primary command buffer becomes invalid.

If the nestedCommandBuffer feature is enabled it is valid usage for vkCmdExecuteCommands to also be recorded to a secondary command buffer.
