wresize - resize a curses window
int wresize(WINDOW *win, int lines, int columns);
wresize function 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
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 dimensions fit within the actual screen dimensions.
