# VkImportMemoryZirconHandleInfoFUCHSIA(3) Manual Page

## Name

VkImportMemoryZirconHandleInfoFUCHSIA - Structure specifying import parameters for Zircon handle to external memory

## C Specification

The `VkImportMemoryZirconHandleInfoFUCHSIA` structure is defined as:

    // Provided by VK_FUCHSIA_external_memory
    typedef struct VkImportMemoryZirconHandleInfoFUCHSIA {
        VkStructureType                       sType;
        const void*                           pNext;
        VkExternalMemoryHandleTypeFlagBits    handleType;
        zx_handle_t                           handle;
    } VkImportMemoryZirconHandleInfoFUCHSIA;

## Members

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

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

- `handleType` is a VkExternalMemoryHandleTypeFlagBits value specifying the type of `handle`.

- `handle` is a `zx_handle_t` (Zircon) handle to the external memory.

## Description

Valid Usage

- VUID-VkImportMemoryZirconHandleInfoFUCHSIA-handleType-04771
  `handleType` must be VK_EXTERNAL_MEMORY_HANDLE_TYPE_ZIRCON_VMO_BIT_FUCHSIA

- VUID-VkImportMemoryZirconHandleInfoFUCHSIA-handle-04772
  `handle` must be a valid VMO handle

Valid Usage (Implicit)

- VUID-VkImportMemoryZirconHandleInfoFUCHSIA-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_IMPORT_MEMORY_ZIRCON_HANDLE_INFO_FUCHSIA

- VUID-VkImportMemoryZirconHandleInfoFUCHSIA-handleType-parameter
  If `handleType` is not `0`, `handleType` must be a valid VkExternalMemoryHandleTypeFlagBits value

Structure Chaining
