           #include <curses.h>

           int baudrate(void);

           char *longname(void);

           char *termname(void);

## 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 wc.  If no erase character has been defined, the
           routine fails and the location referenced by wc is not changed.

### has_ic, 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(3x).

### 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 wc.  If no line-kill character has been defined,
           the routine fails and the location referenced by wc 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

           X/Open  Curses,  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.
