       The  ddeelleetteellnn and wwddeelleetteellnn routines delete the line under
       the cursor in the window; all lines below the current line
       are  moved  up one line.  The bottom line of the window is
       cleared.  The cursor position does not change.

       The iinnssddeellllnn  and  wwiinnssddeellllnn  routines,  for  positive  _n,
       insert _n lines into the specified window above the current
       line.  The _n bottom  lines  are  lost.   For  negative  _n,
       delete  _n  lines (starting with the one under the cursor),
       and move the remaining lines up.  The bottom _n  lines  are
       cleared.  The current cursor position remains the same.

       The  iinnsseerrttllnn  and  iinnsseerrttllnn routines, insert a blank line
       above the current line and the bottom line is lost.

RREETTUURRNN VVAALLUUEE
       All routines return the integer EERRRR upon failure and an OOKK
       (SVr4  specifies  only  "an integer value other than EERRRR")
       upon successful completion.

PPOORRTTAABBIILLIITTYY
       These functions are described in the XSI Curses  standard,
       Issue  4.   The standard specifies that they return EERRRR on
       failure, but specifies no error conditions.

NNOOTTEESS
       Note that all but wwiinnssddeellllnn may be a macros.

       These routines do not require a hardware  line  delete  or
       insert  feature  in the terminal.  In fact, they won't use
       hardware line delete/insert unless  iiddllookk((......,,  TTRRUUEE))  has
       been set on the current window.
