C Specification

To create a command pool, call:

// Provided by VK_VERSION_1_0
VkResult vkCreateCommandPool(
    VkDevice                                    device,
    const VkCommandPoolCreateInfo*              pCreateInfo,
    const VkAllocationCallbacks*                pAllocator,
    VkCommandPool*                              pCommandPool);


  • device is the logical device that creates the command pool.

  • pCreateInfo is a pointer to a VkCommandPoolCreateInfo structure specifying the state of the command pool object.

  • pAllocator controls host memory allocation as described in the Memory Allocation chapter.

  • pCommandPool is a pointer to a VkCommandPool handle in which the created pool is returned.


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

Valid Usage
  • VUID-vkCreateCommandPool-queueFamilyIndex-01937
    pCreateInfo->queueFamilyIndex must be the index of a queue family available in the logical device device

  • VUID-vkCreateCommandPool-device-05068
    The number of command pools currently allocated from device plus 1 must be less than or equal to the total number of command pools requested via VkDeviceObjectReservationCreateInfo::commandPoolRequestCount specified when device was created

Valid Usage (Implicit)
  • VUID-vkCreateCommandPool-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkCreateCommandPool-pCreateInfo-parameter
    pCreateInfo must be a valid pointer to a valid VkCommandPoolCreateInfo structure

  • VUID-vkCreateCommandPool-pAllocator-null
    pAllocator must be NULL

  • VUID-vkCreateCommandPool-pCommandPool-parameter
    pCommandPool must be a valid pointer to a VkCommandPool handle

Return Codes
On success, this command returns

On failure, this command returns
