| 13 char erasechar(void); | |
| 14 bool has_ic(void); | |
| 15 bool has_il(void); | |
| 16 char killchar(void); | |

| 18 chtype termattrs(void); | |
| 19 attr_t term_attrs(void); | |
| 20 char *termname(void); | |
| 21 | |
| 22 int erasewchar(wchar_t *ch); | |
| 23 int killwchar(wchar_t *ch); | |

| 25 char wordchar(void); | |
| 26 | |
| 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. | |
