-.SH DESCRIPTION
-The \fBunctrl\fR routine returns a character string which is a printable
-representation of the character \fIc\fR, ignoring attributes.
-Control characters are displayed in the \fB^\fR\fIX\fR notation.
-Printing characters are displayed as is.
-The corresponding \fBwunctrl\fR returns a printable representation of
-a wide-character.
-.PP
-The \fBkeyname\fR routine returns a character string corresponding to the key \fIc\fR.
-Control characters are displayed in the \fB^\fR\fIX\fR notation.
-Values above 128 are either meta characters, shown in the \fBM-\fR\fIX\fR notation,
-or the names of function keys, or null.
-The corresponding \fBkey_name\fR returns a character string corresponding
-to the wide-character value \fIw\fR.
-The two functions do not return the same set of strings;
-the latter returns null where the former would display a meta character.
-.PP
-The \fBfilter\fR routine, if used, must be called before \fBinitscr\fR or
-\fBnewterm\fR are called.  The effect is that, during those calls, \fBLINES\fR
-is set to 1; the capabilities \fBclear\fR, \fBcup\fR, \fBcud\fR, \fBcud1\fR,
-\fBcuu1\fR, \fBcuu\fR, \fBvpa\fR are disabled; and the \fBhome\fR string is
-set to the value of \fBcr\fR.
-.PP
-The \fBnofilter\fP routine cancels the effect of a preceding \fBfilter\fP
-call.
-That allows the caller to initialize a screen on a different device,
-using a different value of \fB$TERM\fP.
-The limitation arises because the \fBfilter\fP routine modifies the
-in-memory copy of the terminal information.
-.PP
-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
-\fBcurses\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).
-Note that setting \fBLINES\fR or \fBCOLUMNS\fR overrides the
-corresponding size which may be obtained from the operating system.
-.PP
-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.
-.PP
-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.
-.PP
-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.
-If no padding character is specified, this uses \fBnapms\fR to perform the delay.
-.PP
-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 \fBOK\fR (SVr4 specifies only "an integer value other than
-\fBERR\fR") upon successful completion.
-.PP
-Routines that return pointers return \fBNULL\fR on error.
-.PP
-X/Open does not define any error conditions.
-In this implementation
-.RS
-.TP 5
-\fBflushinp\fR
-returns an error if the terminal was not initialized.
-.TP 5
-\fBputwin\fP
-returns an error if the associated \fBfwrite\fP calls return an error.
-.RE
-.SH PORTABILITY
-The XSI Curses standard, Issue 4 describes these functions.
-It states that \fBunctrl\fR and \fBwunctrl\fR will return a null pointer if
-unsuccessful, but does not define any error conditions.
-This implementation checks for three cases:
-.RS
-.TP 5
--
-the parameter is a 7-bit US-ASCII code.
-This is the case that X/Open Curses documented.
-.TP 5
--
-the parameter is in the range 128-159, i.e., a C1 control code.
-If \fBuse_legacy_coding\fP has been called with a \fB2\fP parameter,
-\fBunctrl\fP returns the parameter, i.e., a one-character string with
-the parameter as the first character.
-Otherwise, it returns ``~@'', ``~A'', etc., analogous to ``^@'', ``^A'', C0 controls.
-.IP
-X/Open Curses does not document whether \fBunctrl\fP can be called before
-initializing curses.
-This implementation permits that,
-and returns the ``~@'', etc., values in that case.
-.TP 5
--
-parameter values outside the 0 to 255 range.
-\fBunctrl\fP returns a null pointer.
-.RE
-.PP
-The SVr4 documentation describes the action of \fBfilter\fR only in the vaguest
-terms.  The description here is adapted from the XSI Curses standard (which
-erroneously fails to describe the disabling of \fBcuu\fR).
-.PP
-The strings returned by \fBunctrl\fR in this implementation are determined
-at compile time,
-showing C1 controls from the upper-128 codes with a `~' prefix rather than `^'.
-Other implementations have different conventions.
-For example, they may show both sets of control characters with `^',
-and strip the parameter to 7 bits.
-Or they may ignore C1 controls and treat all of the upper-128 codes as
-printable.
-This implementation uses 8 bits but does not modify the string to reflect
-locale.
-The \fBuse_legacy_coding\fP function allows the caller to
-change the output of \fBunctrl\fP.
-.PP
-Likewise, the \fBmeta\fP function allows the caller to change the
-output of \fBkeyname\fP, i.e.,
-it determines whether to use the `M-' prefix
-for ``meta'' keys (codes in the range 128 to 255).
-Both \fBuse_legacy_coding\fP and \fBmeta\fP succeed only after
-curses is initialized. 
-X/Open Curses does not document the treatment of codes 128 to 159.
-When treating them as ``meta'' keys
-(or if \fBkeyname\fP is called before initializing curses),
-this implementation returns strings ``M-^@'', ``M-^A'', etc.
-.PP
-The \fBkeyname\fP function may return the names of user-defined
-string capabilities which are defined in the terminfo entry via the \fB-x\fP
-option of \fBtic\fP.
-This implementation automatically assigns at run-time keycodes to 
-user-defined strings which begin with "k".
-The keycodes start at KEY_MAX, but are not guaranteed to be 
-the same value for different runs because user-defined codes are
-merged from all terminal descriptions which have been loaded.
-.PP
-The \fBnofilter\fP routine is specific to ncurses.
-It was not supported on Version 7, BSD or System V implementations.
-It is recommended that any code depending on ncurses extensions
-be conditioned using NCURSES_VERSION.
