environment query routines
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.
The erasechar routine returns the user's current erase character.
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.
The killchar routine returns the user's current line kill character.
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.
If a given terminal doesn't support a video attribute that an application program is try-
ing to use, curses may substitute a different video attribute for it. The termattrs func-
tion returns a logical OR of all video attributes supported by the terminal. This infor-
mation is useful when a curses program needs complete control over the appearance of the
The termname routine returns the value of the environmental variable TERM (truncated to 14
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.
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.
