+  Name:                                                         delch
+
+  Synopsis:
+        int delch(void);
+        int wdelch(WINDOW *win);
+        int mvdelch(int y, int x);
+        int mvwdelch(WINDOW *win, int y, int x);
+
+  Description:
+        The character under the cursor in the window is deleted.  All
+        characters to the right on the same line are moved to the left
+        one position and the last character on the line is filled with
+        a blank.  The cursor position does not change (after moving to
+        y, x if coordinates are specified).
+
+  Return Value:
+        All functions return OK on success and ERR on error.
