NAME
       ddeelleetteellnn,  wwddeelleetteellnn, iinnssddeellllnn, wwiinnssddeellllnn, iinnsseerrttllnn, wwiinnsseerrttllnn - delete
       and insert lines in a ccuurrsseess window

SYNOPSIS
       ##iinncclluuddee <>

       iinntt ddeelleetteellnn((vvooiidd));;
       iinntt wwddeelleetteellnn((WWIINNDDOOWW **wwiinn));;
       iinntt iinnssddeellllnn((iinntt nn));;
       iinntt wwiinnssddeellllnn((WWIINNDDOOWW **wwiinn,, iinntt nn));;
       iinntt iinnsseerrttllnn((vvooiidd));;
       iinntt wwiinnsseerrttllnn((WWIINNDDOOWW **wwiinn));;

DESCRIPTION
       The ddeelleetteellnn and wwddeelleetteellnn 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  iinnssddeellllnn  and  wwiinnssddeellllnn  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  iinnsseerrttllnn and wwiinnsseerrttllnn routines insert a blank line above the cur-
       rent line and the bottom line is lost.

RREETTUURRNN VVAALLUUEE
       All routines return the integer EERRRR upon failure and an OOKK (SVr4 speci-
       fies  only  "an  integer value other than EERRRR") upon successful comple-
       tion.

       X/Open defines no error conditions.  In  this  implementation,  if  the
       window parameter is null, an error is returned.

PPOORRTTAABBIILLIITTYY
       These functions are described in the XSI Curses standard, Issue 4.  The
       standard specifies that they return EERRRR on failure,  but  specifies  no
       error conditions.

NNOOTTEESS
       Note that all but wwiinnssddeellllnn may be 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 iiddllookk((......,, TTRRUUEE)) has been set on the current window.
