15 bool has_il(void);
16 char killchar(void);
17 char *longname(void);
18 chtype termattrs(void);
19 attr_t term_attrs(void);
20 char *termname(void);

22 int erasewchar(wchar_t *ch);
23 int killwchar(wchar_t *ch);

25 char wordchar(void);

27 Description:
28 baudrate() is supposed to return the output speed of the
29 terminal. In PDCurses, it simply returns INT_MAX.
30
31 has_ic and has_il() return TRUE. These functions have meaning in
32 some other implementations of curses.
33
34 erasechar() and killchar() return ^H and ^U, respectively -- the
35 ERASE and KILL characters. In other curses implementations,
36 these may vary by terminal type. erasewchar() and killwchar()
37 are the wide-character versions; they take a pointer to a
38 location in which to store the character, and return OK or ERR.
39
40 longname() returns a pointer to a static area containing a
41 verbose description of the current terminal. The maximum length
42 of the string is 128 characters. It is defined only after the
43 call to initscr() or newterm().
44
45 termname() returns a pointer to a static area containing a
46 short description of the current terminal (14 characters).
47
48 termattrs() returns a logical OR of all video attributes
49 supported by the terminal.
50
51 wordchar() is a PDCurses extension of the concept behind the
52 functions erasechar() and killchar(), returning the "delete
53 word" character, ^W.
