| | int mvchgat(int y, int x, int n, attr_t attr, short color, const void *opts); |
| | int mvwchgat(WINDOW *win, int y, int x, int n, attr_t attr, short color, const void *opts); |

These functions change the renditions of the next n characters in the current or specified window (or of the remaining characters on the current or specified line, if n is -1), beginning at the current or specified cursor position. The attributes and colors are specified by attr and color as for setcchar(3XCURSES).
These function neither update the cursor nor perform wrapping.
A value of n that is greater than the remaining characters on a line is not an error.
The opts argument is reserved for definition in a future release. Currently, the application must provide a null pointer for opts.
