-These routines write the characters of the (null-terminated) character string
-\fIstr\fR on the given window. It is similar to calling \fBwaddch\fR once for
-each character in the string. The four routines with \fIn\fR as the last
-argument write at most \fIn\fR characters. If \fIn\fR is -1, then the
-entire string will be added.
