The window cursor is not advanced. These routines work faster than waddnstr. On the other hand, they do not perform checking (such as for the newline, backspace, or carriage return characters), they do not advance the current cursor position, they do not expand other control characters to ^-escapes, and they truncate the string if it crosses the right margin, rather than wrapping it around to the new line.
These routines end successfully on encountering a null cchar_t, or when they have filled the current line. If a complex character cannot completely fit at the end of the current line, the remaining columns are filled with the background character and rendition.
