Unsafe
The position of the window cursor is not advanced. These routines works faster than waddnstr() (see curs_addstr(3X) ) because they merely copy chstr into the window image structure. On the other hand, care must be taken when using these functions because they do not perform any kind of checking (such as for the newline character), they do not advance the current cursor position, and they truncate the string, rather then wrapping it around to the next line.
The header <curses.h> automatically includes the headers <stdio.h> and <unctrl.h>.
Note that all routines except waddchnstr() and waddchstr() may be macros.
