# vkGetDataGraphPipelineSessionMemoryRequirementsARM(3) Manual Page

## Name

vkGetDataGraphPipelineSessionMemoryRequirementsARM - Get the memory requirements of a data graph pipeline session

Loading… please wait.

## C Specification

To determine the memory requirements for a data graph pipeline session, call:

    // Provided by VK_ARM_data_graph
    void vkGetDataGraphPipelineSessionMemoryRequirementsARM(
        VkDevice                                    device,
        const VkDataGraphPipelineSessionMemoryRequirementsInfoARM* pInfo,
        VkMemoryRequirements2*                      pMemoryRequirements);

## Parameters

- `device` is the logical device that owns the data graph pipeline session.

- `pInfo` is a pointer to a VkDataGraphPipelineSessionMemoryRequirementsInfoARM structure containing parameters for the memory requirements query.

- `pMemoryRequirements` is a pointer to a VkMemoryRequirements2 structure in which the memory requirements of the data graph pipeline session object are returned.

## Description

Valid Usage

- VUID-vkGetDataGraphPipelineSessionMemoryRequirementsARM-bindPoint-09784
  The `bindPoint` member of `pInfo` must have been returned as part of a VkDataGraphPipelineSessionBindPointRequirementARM whose `bindPointType` member is `VK_DATA_GRAPH_PIPELINE_SESSION_BIND_POINT_TYPE_MEMORY_ARM` by a prior call to vkGetDataGraphPipelineSessionMemoryRequirementsARM for the `session` member of `pInfo`

Valid Usage (Implicit)

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

- VUID-vkGetDataGraphPipelineSessionMemoryRequirementsARM-pInfo-parameter
  `pInfo` must be a valid pointer to a valid VkDataGraphPipelineSessionMemoryRequirementsInfoARM structure

- VUID-vkGetDataGraphPipelineSessionMemoryRequirementsARM-pMemoryRequirements-parameter
  `pMemoryRequirements` must be a valid pointer to a VkMemoryRequirements2 structure
