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);

Parameters

  • 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.

Description

Valid Usage

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

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-parameter
    If pAllocator is not NULL, pAllocator must be a valid pointer to a valid VkAllocationCallbacks structure

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

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
