# wresize 3x

## NAME

           wresize - resize a curses window

## SYNOPSIS

           #include <curses.h>

           int wresize(WINDOW *win, int lines, int columns);

## DESCRIPTION

           This  is  an  extension to the curses library.  It reallo-
           cates storage for an ncurses window to adjust  its  dimen-
           sions  to  the  specified  values.  If either dimension is
           larger than the  current  values,  the  window's  data  is
           filled with blanks that have the current background rendi-
           tion (as set by wbkgdset) merged into them.

## RETURN VALUE

           The function returns the integer ERR upon failure  and  OK
           on success.  It will fail if either of the dimensions less
           than or equal  to  zero,  or  if  an  error  occurs  while
           (re)allocating memory for the window.

## NOTES

           The only restriction placed on the dimensions is that they
           be greater than zero.  The dimensions are not compared  to
           curses   screen   dimensions  to  simplify  the  logic  of
           resizeterm.  The caller  must  ensure  that  the  window's
           dimensions fit within the actual screen dimensions.

## PORTABILITY

           It is not possible to resize windows with SVr4 curses.

           This  extension of ncurses was introduced in mid-1995.  It
           was adopted in NetBSD curses (2001) and PDCurses (2003).
