# vkBindAccelerationStructureMemoryKHR(3) Manual Page

## Name

vkBindAccelerationStructureMemoryKHR - Bind acceleration structure memory

## C Specification

To attach memory to one or more acceleration structures at a time, call:

    VkResult vkBindAccelerationStructureMemoryKHR(
        VkDevice                                    device,
        uint32_t                                    bindInfoCount,
        const VkBindAccelerationStructureMemoryInfoKHR* pBindInfos);

or the equivalent command

    VkResult vkBindAccelerationStructureMemoryNV(
        VkDevice                                    device,
        uint32_t                                    bindInfoCount,
        const VkBindAccelerationStructureMemoryInfoKHR* pBindInfos);

## Parameters

- `device` is the logical device that owns the acceleration structures and memory.

- `bindInfoCount` is the number of elements in `pBindInfos`.

- `pBindInfos` is a pointer to an array of VkBindAccelerationStructureMemoryInfoKHR structures describing acceleration structures and memory to bind.

## Description

Valid Usage (Implicit)

- `device` must be a valid VkDevice handle

- `pBindInfos` must be a valid pointer to an array of `bindInfoCount` valid VkBindAccelerationStructureMemoryInfoKHR structures

- `bindInfoCount` must be greater than `0`

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`
