Public Delegate Sub IOCompletionCallback(errorCode As UInteger, numBytes As UInteger, pOVERLAP As NativeOverlapped*)
A NativeOverlapped representing an unmanaged pointer to the native overlapped value type.
Requires full trust for the immediate caller. This member cannot be used by partially trusted or transparent code.
