curs_util(3)                                         curs_util(3)

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

       #include <curses.h>

       char *unctrl(chtype c);
       char *keyname(int c);
       void filter(void);
       void use_env(char bool);
       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 correspond-
       ing 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  argu-
       ment,  the  values  of  lines and columns specified in the
       terminfo database will be used, even if environment  vari-
       ables  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


curs_util(3)                                         curs_util(3)

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

       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 func-

       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 <unc-

       curses(3), curs_initscr(3), curs_scr_dump(3).
