| ### Description |
| |
| These functions manipulate a window that contain Soft Label Keys |
| (SLK). To use the SLK functions, a call to slk_init() must be made |
| BEFORE initscr() or newterm(). slk_init() removes 1 or 2 lines from |
| the useable screen, depending on the format selected. |
| |
| The line(s) removed from the screen are used as a separate window, in |
| which SLKs are displayed. |
| |
| slk_init() requires a single parameter which describes the format of |
| the SLKs as follows: |
| |
| 0 3-2-3 format |
| 1 4-4 format |
| 2 4-4-4 format (ncurses extension) |
| 3 4-4-4 format with index line (ncurses extension) |
| 2 lines used |
| 55 5-5 format (pdcurses format) |
| |
| slk_refresh(), slk_noutrefresh() and slk_touch() are analogous to |
| refresh(), noutrefresh() and touch(). |
| |
| ### Return Value |
| |
| All functions return OK on success and ERR on error. |
| |
| ### Portability |
