## Name

vkCreateDescriptorPool - Creates a descriptor pool object

Loading… please wait.

## 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`.

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

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

  - `VK_ERROR_FRAGMENTATION_EXT`
