VB.NET Core Classes in a Nutshell

Name

NativeOverlapped

Synopsis

This structure has the same layout as the Win32 OVERLAPPED structure, with extra reserved data at the end, which is provided for backward compatibility. Create a NativeOverlapped instance by calling Overlapped.Pack(). Each time an instance is created, it must be freed by calling the shared method Overlapped.Free() to avoid a memory leak.
