Hello, 

Im trying to call an ncurses funcion whline(WINDOW *, chtype, int);
which, judging from the ncurses.h is not a macro and gcc -E does not replace it
seems :)

But, the problem is, it just does nothing seems.  I mean, equivalent code  like
this:

initscr();
whline(stdscr, 4194417, 20);
napms(200);
endwin();

in C , draws a 20 col line, but, in D (provided relevant extern (C) is done), 
does not draw a line (the screen/window setup
is ok, and rest).



And, i dont see an error :)



Yeah, extern looks like this  (not compiling)

extern(C)
{
  struct _win_st;
  _win_st* stdscr;
  _win_st* initscr();
  int refresh();
  int endwin();
  int napms(int);
  int whline(_win_st *win, ulong ch, int n);
}

Are you sure that the second parameter of whline should be an ulong ? In 
D it's a 64 bit integer...

Oh !

:P  Thanks, I didnt even think for a sec about that difference (err, not that I
looked carefully at types)

Thanks again, its actually working
