wresize(3X) Library calls wresize(3X) NAME wresize - resize a curses window SYNOPSIS #include <curses.h> int wresize(WINDOW * win, int lines, int columns); DESCRIPTION wresize, an ncurses extension to the curses library, reallocates storage for win, adjusting its dimensions to lines and columns. If either dimen- sion is larger than its current value, ncurses fills the expanded part of the window with the window's background character as configured by wbkgdset(3X) (wide-character API: wbkgrndset(3X)). RETURN VALUE wresize returns OK on success and ERR on failure. It fails if either lines or columns is less than or equal to zero, or if an error occurs while (re)allocating memory for win. NOTES The only restriction placed on the values of lines and columns is that they be greater than zero. They are not compared to the dimensions of the curses screen; this keeps the logic of resizeterm(3X) simple. The caller must ensure that win's dimensions fit within those of the screen. EXTENSIONS wresize is an ncurses(3X) extension, and is not found in SVr4 curses, 4.4BSD curses, or any other previous curses implementation. PORTABILITY Applications employing ncurses extensions should condition their use on the visibility of the NCURSES_VERSION preprocessor macro. NetBSD curses adopted wresize in 2001 (release 1.5.3), and PDCurses in 2004 (version 2.7). It is not possible to resize windows with SVr4 curses. HISTORY Thomas Dickey developed wresize as an extension to BSD curses in 1988, and brought it to ncurses in mid-1995. AUTHORS Thomas Dickey SEE ALSO resizeterm(3X) ncurses 6.6 2025-01-18 wresize(3X)
