| 27 | Description: |
Stefan Reinauer | e11835e | 2011-10-31 12:54:00 -0700 | [diff] [blame] | 28 | baudrate() is supposed to return the output speed of the |
Patrick Georgi | 3b77b72 | 2011-07-07 15:41:53 +0200 | [diff] [blame] | 29 | terminal. In PDCurses, it simply returns INT_MAX. |
| 30 | |
Stefan Reinauer | e11835e | 2011-10-31 12:54:00 -0700 | [diff] [blame] | 31 | has_ic and has_il() return TRUE. These functions have meaning in |
Patrick Georgi | 3b77b72 | 2011-07-07 15:41:53 +0200 | [diff] [blame] | 32 | some other implementations of curses. |
| 33 | |
Stefan Reinauer | e11835e | 2011-10-31 12:54:00 -0700 | [diff] [blame] | 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 |
Patrick Georgi | 3b77b72 | 2011-07-07 15:41:53 +0200 | [diff] [blame] | 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 | |
Stefan Reinauer | e11835e | 2011-10-31 12:54:00 -0700 | [diff] [blame] | 51 | wordchar() is a PDCurses extension of the concept behind the |
| 52 | functions erasechar() and killchar(), returning the "delete |
Patrick Georgi | 3b77b72 | 2011-07-07 15:41:53 +0200 | [diff] [blame] | 53 | word" character, ^W. |
