C Specification

To create a descriptor pool object, call:

// Provided by VK_VERSION_1_0
VkResult vkCreateDescriptorPool(
    VkDevice                                    device,
    const VkDescriptorPoolCreateInfo*           pCreateInfo,
    const VkAllocationCallbacks*                pAllocator,
    VkDescriptorPool*                           pDescriptorPool);


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

  • pCreateInfo is a pointer to a VkDescriptorPoolCreateInfo structure specifying the state of the descriptor pool object.

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

  • pDescriptorPool is a pointer to a VkDescriptorPool handle in which the resulting descriptor pool object is returned.


The created descriptor pool is returned in pDescriptorPool.

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

Valid Usage
  • VUID-vkCreateDescriptorPool-device-05068
    The number of descriptor pools currently allocated from device plus 1 must be less than or equal to the total number of descriptor pools requested via VkDeviceObjectReservationCreateInfo::descriptorPoolRequestCount specified when device was created

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

  • VUID-vkCreateDescriptorPool-pCreateInfo-parameter
    pCreateInfo must be a valid pointer to a valid VkDescriptorPoolCreateInfo structure

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

  • VUID-vkCreateDescriptorPool-pDescriptorPool-parameter
    pDescriptorPool must be a valid pointer to a VkDescriptorPool handle

Return Codes
On success, this command returns

On failure, this command returns
