/**
 * Structure specifying additional attributes of Windows handles exported from a memory.
 * 
 * Description
 * 
 * If this structure is not present, or if {@code pAttributes} is set to {@code 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 "{@code Synchronization Object Security and Access Rights}"¹. Further, if the structure is not present, the access rights will be
 * 
 * {@code DXGI_SHARED_RESOURCE_READ} | {@code DXGI_SHARED_RESOURCE_WRITE}
 * 
 * for handles of the following types:
 * 
 * {@link KHRExternalMemoryCapabilities#VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_KHR EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_KHR} {@link KHRExternalMemoryCapabilities#VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_BIT_KHR EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_BIT_KHR}
 * 
 * And
 * 
 * {@code GENERIC_ALL}
 * 
 * for handles of the following types:
 * 
 * {@link KHRExternalMemoryCapabilities#VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_HEAP_BIT_KHR EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_HEAP_BIT_KHR} {@link KHRExternalMemoryCapabilities#VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE_BIT_KHR EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE_BIT_KHR}
 * 
 * 
 * 1
 * https://msdn.microsoft.com/en-us/library/windows/desktop/ms686670.aspx
 * 
 * 
 * Valid Usage
 * 
 * 
 * If {@link VkExportMemoryAllocateInfoKHR}{@code ::handleTypes} does not include {@link KHRExternalMemoryCapabilities#VK_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_KHR EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT_KHR}, {@link KHRExternalMemoryCapabilities#VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_BIT_KHR EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_BIT_KHR}, {@link KHRExternalMemoryCapabilities#VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_HEAP_BIT_KHR EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_HEAP_BIT_KHR}, or {@link KHRExternalMemoryCapabilities#VK_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE_BIT_KHR EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE_BIT_KHR}, VkExportMemoryWin32HandleInfoKHR must not be in the {@code pNext} chain of {@link VkMemoryAllocateInfo}.
 * 
 * 
 * Valid Usage (Implicit)
 * 
 * 
 * {@code sType} must be {@link KHRExternalMemoryWin32#VK_STRUCTURE_TYPE_EXPORT_MEMORY_WIN32_HANDLE_INFO_KHR STRUCTURE_TYPE_EXPORT_MEMORY_WIN32_HANDLE_INFO_KHR}
 * {@code pNext} must be {@code NULL}
 * If {@code pAttributes} is not {@code NULL}, {@code pAttributes} must be a pointer to a valid {@code SECURITY_ATTRIBUTES} value
 * 
 * 
 * Member documentation
 * 
 * 
 * {@code sType} – the type of this structure.
 * {@code pNext} – {@code NULL} or a pointer to an extension-specific structure.
 * {@code pAttributes} – a pointer to a Windows {@code SECURITY_ATTRIBUTES} structure specifying security attributes of the handle.
 * {@code dwAccess} – a {@code DWORD} specifying access rights of the handle.
 * {@code name} – a NULL-terminated UTF-16 string to associate with the underlying resource referenced by NT handles exported from the created memory.
 *
