       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
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.
