Copy the source and save as user32.decls in the USERLIBS folder of Blitz3d. Then search on Windows folder the file user32.dll and copy it in the USERLIBS folders too. Restart blitz3d. Now if you type for example api_CloseClipboard it will be reconized by blitz3d as a new command. Stop. What and how the single command works is out of my brain capability :P Sorry - Merry Christmas!
