# VkExportMemoryAllocateInfoNV(3) Manual Page

## Name

VkExportMemoryAllocateInfoNV - Specify memory handle types that may be exported

Loading… please wait.

## C Specification

The VkExportMemoryAllocateInfoNV structure is defined as:

    // Provided by VK_NV_external_memory
    typedef struct VkExportMemoryAllocateInfoNV {
        VkStructureType                      sType;
        const void*                          pNext;
        VkExternalMemoryHandleTypeFlagsNV    handleTypes;
    } VkExportMemoryAllocateInfoNV;

## Members

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

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

- `handleTypes` is a bitmask of VkExternalMemoryHandleTypeFlagBitsNV specifying one or more memory handle types that may be exported. Multiple handle types may be requested for the same allocation as long as they are compatible, as reported by vkGetPhysicalDeviceExternalImageFormatPropertiesNV.

## Description

Valid Usage (Implicit)

- VUID-VkExportMemoryAllocateInfoNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_EXPORT_MEMORY_ALLOCATE_INFO_NV`

- VUID-VkExportMemoryAllocateInfoNV-handleTypes-parameter
  `handleTypes` must be a valid combination of VkExternalMemoryHandleTypeFlagBitsNV values
