26 The baudrate routine returns the output speed of the terminal. The
27 number returned is in bits per second, for example 9600, and is an
28 integer.
29
30 The erasechar routine returns the user's current erase character.
31
32 The erasewchar routine stores the current erase character in the loca‐
33 tion referenced by ch. If no erase character has been defined, the
34 routine fails and the location referenced by ch is not changed.
35
36 The has_ic routine is true if the terminal has insert- and delete-
37 character capabilities.
38
39 The has_il routine is true if the terminal has insert- and delete-line
40 capabilities, or can simulate them using scrolling regions. This might
41 be used to determine if it would be appropriate to turn on physical
42 scrolling using scrollok.
43
44 The killchar routine returns the user's current line kill character.
45
46 The killwchar routine stores the current line-kill character in the
47 location referenced by ch. If no line-kill character has been defined,
48 the routine fails and the location referenced by ch is not changed.
49
50 The longname routine returns a pointer to a static area containing a
51 verbose description of the current terminal. The maximum length of a
52 verbose description is 128 characters. It is defined only after the
53 call to initscr or newterm. The area is overwritten by each call to
54 newterm and is not restored by set_term, so the value should be saved
55 between calls to newterm if longname is going to be used with multiple
56 terminals.
57
58 If a given terminal does not support a video attribute that an applica‐
59 tion program is trying to use, curses may substitute a different video
60 attribute for it. The termattrs and term_attrs functions return a log‐
61 ical OR of all video attributes supported by the terminal using A_ and
62 WA_ constants respectively. This information is useful when a curses
63 program needs complete control over the appearance of the screen.
64
65 The termname routine returns the terminal name used by setupterm.
66
68 longname and termname return NULL on error.
69
70 Routines that return an integer return ERR upon failure and OK (SVr4
71 only specifies "an integer value other than ERR") upon successful com‐
72 pletion.
73
75 Note that termattrs may be a macro.
76
78 The XSI Curses standard, Issue 4 describes these functions. It changes
79 the return type of termattrs to the new type attr_t. Most versions of
80 curses truncate the result returned by termname to 14 characters.
