## Name

VkDataGraphPipelineSessionMemoryRequirementsInfoARM - Structure specifying parameters to query the memory requirements of a data graph pipeline session

Loading… please wait.

## C Specification

The `VkDataGraphPipelineSessionMemoryRequirementsInfoARM` structure is defined as:

    // Provided by VK_ARM_data_graph
    typedef struct VkDataGraphPipelineSessionMemoryRequirementsInfoARM {
        VkStructureType                           sType;
        const void*                               pNext;
        VkDataGraphPipelineSessionARM             session;
        VkDataGraphPipelineSessionBindPointARM    bindPoint;
        uint32_t                                  objectIndex;
    } VkDataGraphPipelineSessionMemoryRequirementsInfoARM;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `session` is the data graph pipeline session to query.

- `bindPoint` is the bind point of a data graph pipeline session for which memory requirements are being queried.

- `objectIndex` is the index of the object whose memory requirements are being queried.

## Description

Valid Usage

- VUID-VkDataGraphPipelineSessionMemoryRequirementsInfoARM-objectIndex-09855
  `objectIndex` must be less than the number of objects returned by vkGetDataGraphPipelineSessionBindPointRequirementsARM via VkDataGraphPipelineSessionBindPointRequirementARM::`numObjects` with VkDataGraphPipelineSessionMemoryRequirementsInfoARM::`bindPoint` equal to `bindPoint`

Valid Usage (Implicit)

- VUID-VkDataGraphPipelineSessionMemoryRequirementsInfoARM-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_DATA_GRAPH_PIPELINE_SESSION_MEMORY_REQUIREMENTS_INFO_ARM`

- VUID-VkDataGraphPipelineSessionMemoryRequirementsInfoARM-pNext-pNext
  `pNext` must be `NULL`

- VUID-VkDataGraphPipelineSessionMemoryRequirementsInfoARM-session-parameter
  `session` must be a valid VkDataGraphPipelineSessionARM handle

- VUID-VkDataGraphPipelineSessionMemoryRequirementsInfoARM-bindPoint-parameter
  `bindPoint` must be a valid VkDataGraphPipelineSessionBindPointARM value
