|
|
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.

|
|
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).
