| 44 Description: | |
| 45 border(), wborder(), and box() draw a border around the edge of | |
| 46 the window. If any argument is zero, an appropriate default is | |
| 47 used: | |
| 48 | |
| 49 ls left side of border ACS_VLINE | |
| 50 rs right side of border ACS_VLINE | |
| 51 ts top side of border ACS_HLINE | |
| 52 bs bottom side of border ACS_HLINE | |
| 53 tl top left corner of border ACS_ULCORNER | |
| 54 tr top right corner of border ACS_URCORNER | |
| 55 bl bottom left corner of border ACS_LLCORNER | |
| 56 br bottom right corner of border ACS_LRCORNER | |
| 57 | |
| 58 hline() and whline() draw a horizontal line, using ch, starting | |
| 59 from the current cursor position. The cursor position does not | |
| 60 change. The line is at most n characters long, or as many as | |
| 61 will fit in the window. | |
| 62 | |
| 63 vline() and wvline() draw a vertical line, using ch, starting | |
| 64 from the current cursor position. The cursor position does not | |
| 65 change. The line is at most n characters long, or as many as | |
| 66 will fit in the window. | |
| 67 | |
| 68 Return Value: | |
| 69 These functions return OK on success and ERR on error. | |
