| This is an extension to the curses library. It reallocates storage for |
| an <STRONG>ncurses</STRONG> 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 <STRONG>wbkgdset</STRONG>) merged into them. |
| |
| |
| </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE> |
| The function returns the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> 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. |
| |
| |
| </PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE> |
| The only restriction placed on the dimensions is that they be greater |
| than zero. The dimensions are not compared to <STRONG>curses</STRONG> screen dimensions |
| to simplify the logic of <STRONG>resizeterm</STRONG>. The caller must ensure that the |
| window's dimensions fit within the actual screen dimensions. |
| |
| |
| </PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE> |
| 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). |
