# vkSetBufferCollectionBufferConstraintsFUCHSIA(3) Manual Page

## Name

vkSetBufferCollectionBufferConstraintsFUCHSIA - Set buffer-based constraints for a buffer collection

Loading… please wait.

## C Specification

To set the constraints on a VkBuffer buffer collection, call:

    // Provided by VK_FUCHSIA_buffer_collection
    VkResult vkSetBufferCollectionBufferConstraintsFUCHSIA(
        VkDevice                                    device,
        VkBufferCollectionFUCHSIA                   collection,
        const VkBufferConstraintsInfoFUCHSIA*       pBufferConstraintsInfo);

## Parameters

- `device` is the logical device

- `collection` is the VkBufferCollectionFUCHSIA handle

- `pBufferConstraintsInfo` is a pointer to a VkBufferConstraintsInfoFUCHSIA structure

## Description

`vkSetBufferCollectionBufferConstraintsFUCHSIA` may fail if the implementation does not support the constraints specified in the `bufferCollectionConstraints` structure. If that occurs, vkSetBufferCollectionBufferConstraintsFUCHSIA will return `VK_ERROR_FORMAT_NOT_SUPPORTED`.

Valid Usage

- VUID-vkSetBufferCollectionBufferConstraintsFUCHSIA-collection-06403
  `vkSetBufferCollectionImageConstraintsFUCHSIA` or `vkSetBufferCollectionBufferConstraintsFUCHSIA` must not have already been called on `collection`

Valid Usage (Implicit)

- VUID-vkSetBufferCollectionBufferConstraintsFUCHSIA-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkSetBufferCollectionBufferConstraintsFUCHSIA-collection-parameter
  `collection` must be a valid VkBufferCollectionFUCHSIA handle

- VUID-vkSetBufferCollectionBufferConstraintsFUCHSIA-pBufferConstraintsInfo-parameter
  `pBufferConstraintsInfo` must be a valid pointer to a valid VkBufferConstraintsInfoFUCHSIA structure

- VUID-vkSetBufferCollectionBufferConstraintsFUCHSIA-collection-parent
  `collection` must have been created, allocated, or retrieved from `device`

Return Codes

On success, this command returns

  - `VK_SUCCESS`

On failure, this command returns

  - `VK_ERROR_INITIALIZATION_FAILED`

  - `VK_ERROR_OUT_OF_HOST_MEMORY`

  - `VK_ERROR_FORMAT_NOT_SUPPORTED`
