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(3NCURSES).

   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.
