wresize(3)          UNIX Programmer's Manual           wresize(3)

NAME

     wresize - resize a curses window

SYNOPSIS

     #include <curses.h>

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

DESCRIPTION

     The wresize function reallocates storage for an ncurses win-
     dow 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 wbkgndset) 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 dimen-
     sions fit within the actual screen dimensions.
