 .SH SYNOPSIS

-\fBint wresize(WINDOW *\fP\fIwin\fP\fB, int \fP\fIlines\fP\fB, int \fP\fIcolumns\fP\fB);\fP

 .SH DESCRIPTION
 .SH DESCRIPTION

-This is an extension to the curses library.
-It reallocates storage for an \fBncurses\fP
-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 \fBwbkgdset\fP) merged into them.
+This \fI\%ncurses\fP extension to standard \fIcurses\fP reallocates
+storage for a \fIcurses\fP window to adjust its dimensions to the
+specified values.
+If either dimension is larger than its current value,
+the expanded part of the window is filled with blanks merged with
+current background rendition
+(as set by \fB\%wbkgdset\fP(3X)).

 .SH RETURN VALUE
 .SH RETURN VALUE

-The function returns the integer \fBERR\fP upon failure and \fBOK\fP on success.
-It will fail if either of the dimensions less than or equal to zero,
+\fB\%wresize\fP returns \fBERR\fP upon failure and \fBOK\fP on success.
+It will fail if either of the dimensions is less than or equal to zero,

 or if an error occurs while (re)allocating memory for the window.
 .SH NOTES
 or if an error occurs while (re)allocating memory for the window.
 .SH NOTES

-The only restriction placed on the dimensions is that they be greater than zero.
-The dimensions are not compared to \fBcurses\fP screen dimensions to
-simplify the logic of \fBresizeterm\fP.
+The only restriction placed on the dimensions is that they be greater
+than zero.
+They are \fInot\fP compared to the \fIcurses\fP screen dimensions;
+this keeps the logic of \fB\%resizeterm\fP(3X) simple.

 The caller must ensure that the window's dimensions fit within the
 actual screen dimensions.
 .SH PORTABILITY
