Prototypes or Alias for called functions

[matty47]

Does Liberty Basic have the ability to "map" functions called from an external dll to a name? or handle? For example could the following

Calldll #x3d, "WindowCreate",0 as double,0 as double,640 as double,480 as double,1 as double,result as double
be aliased/mapped to something like

xWindowCreate(double,double,double,double,double) as double
and then be used like

result = xWindowCreate(0,0,640,480,1)
Thanks for any replies

Actually it is done almost every time.
You create LB wrapper and use it as ordinary function, like this
(From
libertybasiccom.proboards.com/thread/1824/simulate-mouse-click
)

result = SetCursorPos(desiredX, desiredY)
...
Function SetCursorPos(X, Y)
  CallDLL #user32, "SetCursorPos", X              As long, _
                                   Y              As long, _
                                   SetCursorPos   As long
End Function

Thanks for the quick response. Once shown it seems so obvious!

The LBPE covers API calls. While I see you understand the API the tutorial may cover a quirk or two calling the API from within Liberty.

Thanks. I did purchase the API book at LuLu some time ago but it seemed to concentrate a ot on the windows API
