||
| 11 | |||
| 12 | int delch(void); |
||
| 13 | int wdelch(WINDOW *win); |
||
| 14 | int mvdelch(int y, int x); |
||
| 15 | int mvwdelch(WINDOW *win, int y, int x); |
||
| 16 | |||
| 17 | ### Description |
||
| 18 | |||
| 19 | The character under the cursor in the window is deleted. All |
||
| 20 | characters to the right on the same line are moved to the left one |
||
| 21 | position and the last character on the line is filled with a blank. |
||
| 22 | The cursor position does not change (after moving to y, x if |
||
| 23 | coordinates are specified). |
||
| 24 | |||
| 25 | ### Return Value |
||
| 26 | |||
| 27 | All functions return OK on success and ERR on error. |
||
| 28 | |||
