baudrate
baudrate returns the line speed of the terminal, an integer value
measured in bits per second, for example 9600.
erasechar, erasewchar
erasechar returns the terminal's erase character.
erasewchar stores the erase character in the location referenced
by wc. If no erase character has been defined, it fails and the
location referenced by wc is not changed.
has_ic, has_il
has_ic returns TRUE if the terminal has insert- and delete-
character capabilities.
has_il returns TRUE if the terminal has insert- and delete-line
capabilities, or can simulate them using scrolling regions. It
might be used to determine whether it would be appropriate to use
scrollok(3X) to turn on scrolling.
killchar, killwchar
killchar returns the terminal's line kill character.
killwchar stores the line-kill character in the location
referenced by wc. If no line-kill character has been defined, it
fails and the location referenced by wc is not changed.
longname
longname returns a pointer to static storage containing a verbose
description of the terminal being managed by curses. The maximum
length of a verbose description is 128 characters. The storage is
populated only after initscr(3X) or newterm(3X) is called. This
storage is overwritten by each call to newterm and not restored by
set_term(3X), so its contents should be saved between calls to
initscr or newterm if longname is 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. termattrs and term_attrs 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
termname returns the terminal name used by setupterm(3X).
longname and termname return NULL on error.
Functions that return an integer return ERR upon failure and OK
upon success.
erasewchar, killwchar, and term_attrs are part of ncurses's wide-
character API, and are not available in its non-wide-character
configuration.
termattrs may be implemented as a macro.
X/Open Curses Issue 4 describes these functions.
SVr4 describes a successful return value only as “an integer value
other than ERR”.
Most versions of curses truncate the string returned by termname
to 14 characters.
4BSD (1980) introduced longname.
SVr2 (1984) added baudrate, erasechar, killchar, has_ic, and
has_il.
SVr3 (1987) supplied termname. Later that year, SVr3.1 brought
termattrs.
X/Open Curses Issue 4 (1995) specified erasewchar, killwchar, and
term_attrs.
