4115 :: Importc by ordinal instead of name? (Windows)

• jdm (orginal) [2018-08-07T22:42:38+02:00] view original

  Hi, I would like to call the following Windows DLL function from Nim (here the declaration for C#):

  [DllImport("uxtheme.dll", EntryPoint = "#96", CharSet = CharSet.Unicode, PreserveSig = true)] internal static extern uint GetImmersiveColorTypeFromName(

  string name);

  The problem is, the function is not "exported" in the DLL, since it is not a public API. It is present, but can only be called by ordinal number. I tried something like:

  proc GetImmersiveColorTypeFromName*(name: cwstring): uint32 {. stdcall, dynlib: "uxtheme", importc: "#96" .}

  but that is not supported. Is there any way to access this function from Nim, or do I have to resort to LoadLibrary?

  You have to resort to LoadLibrary indeed, but you could also patch lib/pure/dynlib.nim and a Windows specific extension. And create a PR please. :-)
