+.SH DESCRIPTION
+The \fBunctrl\fR macro expands to a character string which is a printable
+representation of the character \fIc\fR.  Control characters are displayed in
+the \fB^\fR\fIX\fR notation.  Printing characters are displayed as is.
+
+The \fBkeyname\fR routine returns a character string corresponding to
+the key \fIc\fR.
+
+The \fBfilter\fR routine, if used, must be called before \fBinitscr\fR or
+\fBnewterm\fR are called.  It makes \fBncurses\fR think that there is a
+one-line screen.  \fBncurses\fR does not use any terminal capabilities
+that assume that they know on what line of the screen the cursor is
+positioned.
+
+The \fBuse_env\fR routine, if used, is called before \fBinitscr\fR or
+\fBnewterm\fR are called.  When called with \fBFALSE\fR as an
+argument, the values of \fBlines\fR and \fBcolumns\fR specified in the
+\fIterminfo\fR database will be used, even if environment variables
+\fBLINES\fR and \fBCOLUMNS\fR (used by default) are set, or if
+\fBncurses\fR is running in a window (in which case default behavior
+would be to use the window size if \fBLINES\fR and \fBCOLUMNS\fR are
+not set).
+
+The \fBputwin\fR routine writes all data associated with window \fIwin\fR into
+the file to which \fIfilep\fR points.  This information can be later retrieved
+using the \fBgetwin\fR function.
+
+The \fBgetwin\fR routine reads window related data stored in the file by
+\fBputwin\fR.  The routine then creates and initializes a new window using that
+data.  It returns a pointer to the new window.
+
+The \fBdelay_output\fR routine inserts an \fIms\fR millisecond pause
+in output.  This routine should not be used extensively because
+padding characters are used rather than a CPU pause.
+
+The \fBflushinp\fR routine throws away any typeahead that has been typed by the
+user and has not yet been read by the program.
+.SH RETURN VALUE
+Except for \fBflushinp\fR, routines that return an integer return
+\fBERR\fR upon failure and an integer value other than \fBERR\fR upon
+successful completion.
+
+\fBflushinp\fR always returns \fBOK\fR.
+
+Routines that return pointers return \fBNULL\fR on error.
+.SH BUGS
+The \fBfilter\fR and \fBdelay_output\fR entry points are not yet
+supported in ncurses 1.8.1.
+.SH NOTES
+Note that \fBunctrl\fR is a macro, which is defined in <\fBunctrl.h\fR>.
