| When slink:VkExportMemoryAllocateInfoNV::pname:handleTypes includes |
| ename:VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_NV, add a |
| sname:VkExportMemoryWin32HandleInfoNV to the pname:pNext chain of the |
| slink:VkExportMemoryAllocateInfoNV structure to specify security attributes |
| and access rights for the memory object's external handle. |
| |
| The sname:VkExportMemoryWin32HandleInfoNV structure is defined as: |
| |
| include::../../api/structs/VkExportMemoryWin32HandleInfoNV.txt[] |
| |
| * pname:sType is the type of this structure. |
| * pname:pNext is `NULL` or a pointer to an extension-specific structure. |
| * pname:pAttributes is a pointer to a Windows code:SECURITY_ATTRIBUTES |
| structure specifying security attributes of the handle. |
| * pname:dwAccess is a code:DWORD specifying access rights of the handle. |
| |
| If this structure is not present, or if pname:pAttributes is set to `NULL`, |
| default security descriptor values will be used, and child processes created |
| by the application will not inherit the handle, as described in the MSDN |
| documentation for "`Synchronization Object Security and Access Rights`"[1]. |
| Further, if the structure is not present, the access rights will be |
| |
| DXGI_SHARED_RESOURCE_READ | DXGI_SHARED_RESOURCE_WRITE |
