I'm trying to compile in Mono on Lubuntu 16.04.1 a very helpful open-source Windows program, Ketarin.It uses a function, GetUpdateRect, which it finds in user32.dll, using this code:  [DllImport(user32.dll, EntryPoint = GetUpdateRect, CharSet = CharSet.Auto)]private static extern IntPtr GetUpdateRectInternal(IntPtr hWnd, ref Rectangle r, bool eraseBackground);This is a non-portable, Windows-specific function/system-call, so I guess I'm asking if anyone can point me to functions or methods available via Mono on Linux that can do what GetUpdateRect does on Windows.Is there a standard list of equivalents between Windows functions and Mono-on-Linux functions?And maybe I need to ask where the people who port Windows programs to run on Linux hang out.Thanks for thinking about these things.
Equivalent in Mono on Linux of GetUpdateRect on Windows?
