.SH DESCRIPTION
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,
up to the maximum number of characters that will fit on the line,
or until a terminating null is reached.
.SH RETURN VALUE
All routines return the integer \fBERR\fR upon failure and \fBOK\fR on success
(the SVr4 manuals specify only "an integer value other than \fBERR\fR") upon
successful completion.
.PP
X/Open does not define any error conditions.
This implementation returns an error
if the window pointer is null or
if the string pointer is null or
if the corresponding calls to \fBwaddch\fP return an error.
.SH NOTES
Note that all of these routines except \fBwaddstr\fR and \fBwaddnstr\fR may be
macros.
.SH PORTABILITY
All these entry points are described in the XSI Curses standard, Issue 4.  The
XSI errors EILSEQ and EOVERFLOW, associated with extended-level conformance,
are not yet detected.
