wresize(3ncurses)

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 reallocates storage for
   an ncurses window to adjust its dimensions 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  rendition  (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).
