       The  baudrate  routine  returns  the output speed of the terminal.  The
       number returned is in bits per second, for  example  9600,  and  is  an

erasechar, erasewchar

       The erasechar routine returns the user's current erase character.

       The  erasewchar routine stores the current erase character in the loca-
       tion referenced by ch.  If no erase character  has  been  defined,  the
       routine fails and the location referenced by ch is not changed.

has_is, has_il

       The  has_ic  routine  is  true  if the terminal has insert- and delete-
       character capabilities.

       The has_il routine is true if the terminal has insert- and  delete-line
       capabilities, or can simulate them using scrolling regions.  This might
       be used to determine if it would be appropriate  to  turn  on  physical
       scrolling using scrollok.

killchar, killwchar

       The killchar routine returns the user's current line kill character.

       The  killwchar  routine  stores  the current line-kill character in the
       location referenced by ch.  If no line-kill character has been defined,
       the routine fails and the location referenced by ch is not changed.


       The  longname  routine  returns a pointer to a static area containing a
       verbose description of the current terminal.  The maximum length  of  a
       verbose  description  is  128 characters.  It is defined only after the
       call to initscr or newterm.  The area is overwritten by  each  call  to
       newterm  and  is not restored by set_term, so the value should be saved
       between calls to newterm if longname is going to be used with  multiple

termattrs, term_attrs

       If a given terminal does not support a video attribute that an applica-
       tion program is trying to use, curses may substitute a different  video
       attribute for it.  The termattrs and term_attrs functions return a log-
       ical OR of all video attributes supported by the terminal using A_  and
       WA_  constants  respectively.  This information is useful when a curses
       program needs complete control over the appearance of the screen.


       The termname routine returns the terminal name used by setupterm.


       longname and termname return NULL on error.

       Routines that return an integer return ERR upon failure  and  OK  (SVr4
       only  specifies "an integer value other than ERR") upon successful com-


       Note that termattrs may be a macro.


       The XSI Curses standard, Issue 4 describes these functions.  It changes
       the  return type of termattrs to the new type attr_t.  Most versions of
       curses truncate the result returned by termname to 14 characters.
