DESCRIPTION

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

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

       The  erasewchar  routine  stores the current erase character in the location 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.

   longname
       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 terminals.

   termattrs, term_attrs
       If  a  given  terminal  does  not support a video attribute that an application program is
       trying to use, curses may substitute a different video attribute for  it.   The  termattrs
       and  term_attrs  functions  return  a  logical 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.

   termname
       The termname routine returns the terminal name used by setupterm.

RETURN VALUE

       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 completion.

NOTES

       Note that termattrs may be a macro.

PORTABILITY

       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.
