  wresize()

  NAME

    wresize() - resize a curses window

  SYNOPSIS

    #include 

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

  DESCRIPTION

    The wresize(3) function adjusts the dimensions of an ncurses window to the
    specified values, reallocating storage as necessary.

    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. If the current cursor position is
    outside the retained area of the window, the cursor is moved to within the
    nearest window edge. Window data is otherwise preserved.

    This function will fail if either of the new dimensions less than or equal
    to zero, or if memory cannot be allocated or reallocated for the window.

    Note that wresize(3) performs non-reentrant malloc() operations, so it
    isn't advisable to resize from within an interrupt handler. Instead, have
    your handler set an event flag to be interpreted next time around your
    program's command loop.

  PORTABILITY

    This call was designed for ncurses and is not found in SVr4 curses, 4.4BSD
    curses, or any other previous version of curses. It is recommended that
    you conditionalize all code depending on it with the symbol NCURSES.

  RETURN VALUE

    The function returns the integer ERR upon failure and OK on success.
