- resize a curses window
int wresize(WINDOW *win, int lines, int columns);
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.
The function returns the integer ERR
upon failure and OK
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.
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.
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).
