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);

Parameters

  • 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.

Description

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

  • VUID-vkCreateDescriptorPool-device-queuecount
    The device must have been created with at least 1 queue

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
