NAME
       copywin - overlay or overwrite any portion of window

SYNOPSIS
       cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib \
       -R /usr/xpg4/lib -lcurses [ library... ]

       c89 [ flag... ] file... -lcurses [ library... ]

       #include <curses.h>

       int copywin(const WINDOW *srcwin, WINDOW *dstwin, int sminrow, int smincol,
            int dminrow, int dmincol, int dmaxrow, int dmaxcol, int overlay);

PARAMETERS
       srcwin     Is a pointer to the source window to be copied.


       dstwin     Is  a  pointer  to the destination window to be overlayed or
                  overwritten.


       sminrow    Is the row coordinate of the upper left corner of  the  rec‐
                  tangular area on the source window to be copied.


       smincol    Is  the  column  coordinate  of the upper left corner of the
                  rectangular area on the source window to be copied.


       dminrow    Is the row coordinate of the upper left corner of  the  rec‐
                  tangular  area  on the destination window to be overlayed or
                  overwritten.


       dmincol    Is the column coordinate of the upper  left  corner  of  the
                  rectangular  area  on  destination window to be overlayed or
                  overwritten.


       dmaxrow    Is the row coordinate of the lower right corner of the  rec‐
                  tangular  area  on the destination window to be overlayed or
                  overwritten.


       dmaxcol    Is the column coordinate of the lower right  corner  of  the
                  rectangular  area  on the destination window to be overlayed
                  or overwritten.


       overlay    Is a TRUE or FALSE value that determines whether the  desti‐
                  nation window is overlayed or overwritten.


DESCRIPTION
       The copywin() function provides a finer granularity of control over the
       overlay(3XCURSES) and overwrite(3XCURSES) functions.  As  in  the  pre‐
       fresh()  function  (see  newpad(3XCURSES)), a rectangle is specified in
       the destination window, (dminrow, dmincol) and (dmaxrow, dmaxcol),  and
       the upper-left-corner coordinates of the source window, (smincol, smin‐
       row). If overlay is TRUE, then copying is non-destructive, as in  over‐
       lay().  If  overlay  is FALSE, then copying is destructive, as in over‐
       write().

RETURN VALUES
       Upon successful completion, the copywin() function returns  OK.  Other‐
       wise, it returns ERR.

ERRORS
       No errors are defined.
