       unctrl,	keyname,  filter, use_env, putwin, getwin, delay_output, flushinp - miscellaneous
       curses utility routines

       #include <curses.h>

       char *unctrl(chtype c);
       char *keyname(int c);
       void filter(void);
       void use_env(bool f);
       int putwin(WINDOW *win, FILE *filep);
       WINDOW *getwin(FILE *filep);
       int delay_output(int ms);
       int flushinp(void);

       The unctrl macro expands to a character string which is a printable representation of  the
       character  c.   Control	characters are displayed in the ^X notation.  Printing characters
       are displayed as is.

       The keyname routine returns a character string corresponding to the key c.

       The filter routine, if used, must be called before initscr or  newterm  are  called.   The
       effect  is  that, during those calls, LINES is set to 1; the capabilities clear, cup, cud,
       cud1, cuu1, cuu, vpa are disabled; and the home string is set to the value of cr.

       The use_env routine, if used, is called before initscr or newterm are called.  When called
       with FALSE as an argument, the values of lines and columns specified in the terminfo data-
       base will be used, even if environment variables LINES and COLUMNS (used by  default)  are
       set,  or  if curses is running in a window (in which case default behavior would be to use
       the window size if LINES and COLUMNS are not set).

       The putwin routine writes all data associated with window win into the file to which filep
       points.	This information can be later retrieved using the getwin function.

       The  getwin  routine  reads window related data stored in the file by putwin.  The routine
       then creates and initializes a new window using that data.  It returns a  pointer  to  the
       new window.

       The  delay_output  routine inserts an ms millisecond pause in output.  This routine should
       not be used extensively because padding characters are used rather than a CPU pause.

       The flushinp routine throws away any typeahead that has been typed by the user and has not
       yet been read by the program.

       Except  for flushinp, routines that return an integer return ERR upon failure and OK (SVr4
       specifies only "an integer value other than ERR") upon successful completion.

       flushinp always returns OK.

       Routines that return pointers return NULL on error.

       The XSI Curses standard, Issue 4 describes these functions.

       The SVr4 documentation describes the action of filter only  in  the  vaguest  terms.   The
       description  here  is  adapted  from  the  XSI Curses standard (which erroneously fails to
       describe the disabling of cuu).

       Note that unctrl is a macro, which is defined in <unctrl.h>.
