stdscr or from
  the specified window.
The deleteln() function deletes the screen
    line containing the cursor in the stdscr. The
    wdeleteln() function is the same as the
    deleteln() function, excepting that the line is
    deleted from the window specified by win.
All lines following the deleted line are moved up one line toward the cursor. The last line of the window is cleared. The cursor position is unchanged.
If a scrolling region has been set with the
    setscrreg() or wsetscrreg()
    functions and the current cursor position is inside the scrolling region,
    then only the lines from the current line to the bottom of the scrolling
    region are moved up and the bottom line of the scrolling region cleared.
The functions deleteln() and
    wdeleteln(win) are equivalent
    to winsdelln(stdscr,
    -1) and
    winsdelln(win,
    -1) respectively.
NULL if an
  error is detected. The functions that return an int will return one of the
