+.Sh DESCRIPTION
+These functions modify the attributes of the drawn content on stdscr or
+on the specified window.
+.Pp
+The
+.Fn chgat
+function sets the attributes of the next
+.Fa n
+characters to
+.Fa attr
+and the color pair to
+.Fa color .
+If
+.Fa n
+is negative or larger than the reminder of the line, it gets truncated.
+.Pp
+The
+.Fn wchgat
+is the same as the
+.Fn chgat
+function, excepting that the attributes are changed in the window specified by
+.Fa win .
+.Pp
+The
+.Fn mvchgat
+and
+.Fn mvwchgat
+functions are the same as the
+.Fn chgat
+and
+.Fn wchgat
+functions, respectively, excepting that
+.Fn wmove
+is called to mvoe the cursor to the position specified by
+.Fa y ,
+.Fa x
+before the attributes are changed.
+.Sh RETURN VALUES
+The functions that return an int will return one of the following
+values:
+.Pp
+.Bl -tag -width ERR -compact
+.It Er OK
+The function completed successfully.
+.It Er ERR
+An error occurred in the function.

+.Sh SEE ALSO
+.Xr curses_attributes 3
+.Sh STANDARDS
+The
+.Nx
+Curses library complies with the X/Open Curses specification, part of
+the Single Unix Specification.
+The
+.Fn chgat
+family is an extension and compatible with GNU ncurses.
+.Sh HISTORY
+The Curses package appeared in
+.Bx 4.0 .
+Support for the
+.Fn chgat
+family was added in
+.Nx 6.0 .
