wresize(3X)                                                      wresize(3X)

NAME         top

       wresize - resize a curses window

SYNOPSIS         top

       #include <curses.h>

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

DESCRIPTION         top

       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         top

       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         top

       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         top

       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).

SEE ALSO         top

AUTHOR         top

       Thomas Dickey (from an equivalent function written in 1988 for BSD
       curses).
