public class VkExportMemoryWin32HandleInfoKHR
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure specifying additional attributes of Windows handles exported from a memory.
Description

If VkExportMemoryAllocateInfo is not included in the same pNext chain, this structure is ignored.

If VkExportMemoryAllocateInfo is included in the pNext chain of VkMemoryAllocateInfo with a Windows handleType, but either VkExportMemoryWin32HandleInfoKHR is not included in the pNext chain, or if it is but 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 used depend on the handle type.

For handles of the following types:
- EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT
The implementation must ensure the access rights allow read and write access to the memory.

https://docs.microsoft.com/en-us/windows/win32/sync/synchronization-object-security-and-access-rights

Valid Usage
- If VkExportMemoryAllocateInfo::handleTypes does not include EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT, a VkExportMemoryWin32HandleInfoKHR structure must not be included in the pNext chain of VkMemoryAllocateInfo
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_EXPORT_MEMORY_WIN32_HANDLE_INFO_KHR
- If pAttributes is not NULL, pAttributes must be a valid pointer to a valid SECURITY_ATTRIBUTES value
Layout
```
 struct VkExportMemoryWin32HandleInfoKHR {
     VkStructureType sType();
     void const * pNext();
     SECURITY_ATTRIBUTES const * pAttributes();
     DWORD dwAccess();
     LPCWSTR name();
