+.SH NAME
+\fBresizeterm\fR - change the curses terminal size
+..
+.SH SYNOPSIS
+\fB#include <curses.h>\fR
+
+\fBint resizeterm(int lines, int columns);\fR
+..
+.SH DESCRIPTION
+This is an extension to the curses library.
+It provides callers with a hook into the \fBncurses\fR data to resize windows,
+primarily for use by programs running in an X Window terminal (e.g., xterm).
+The function \fBresizeterm\fR resizes the standard and current windows
+to the specified dimensions, and adjusts other bookkeeping data used by
+the \fBncurses\fR library that record the window dimensions.
+
+When resizing the windows, the function blank-fills the areas that are
+extended. The calling application should fill in these areas with
+appropriate data.
+
+The function attempts to resize all windows.
+However, due to the calling convention of pads,
+it is not possible to resize these
+without additional interaction with the application.
+..
+.SH RETURN VALUE
+The function returns the integer \fBERR\fR upon failure and \fBOK\fR 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 windows.
+..
+.SH NOTES
+While this function is intended to be used to support a signal handler
+(i.e., for SIGWINCH), care should be taken to avoid invoking it in a
+context where \fBmalloc\fR or \fBrealloc\fR may have been interrupted,
+since it uses those functions.
+..
+.PP
+If ncurses is configured to supply its own SIGWINCH handler,
+the \fBresizeterm\fR function ungetch's a \fBKEY_RESIZE\fR which
+will be read on the next call to \fBgetch\fR.
+This is used to alert an application that the screen size has changed,
+and that it should repaint special features such as pads that cannot
+be done automatically.
+..
