 .SH DESCRIPTION
-These routines write the characters of the (null-terminated) character string
+These functions write 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,
+.PP
+The \fImv\fR functions perform cursor movement once, before writing any
+characters.
+Thereafter, the cursor is advanced as a side-effect of writing to the window.
+.PP
+The four functions with \fIn\fR as the last argument
+write at most \fIn\fR characters,
 or until a terminating null is reached.
+If \fIn\fR is \-1, then the entire string will be added.
 .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.
+All functions return the integer \fBERR\fR upon failure and \fBOK\fR on success.
+.PP
+X/Open does not define any error conditions.
+This implementation returns an error
+.bP
+if the window pointer is null or
+.bP
+if the string pointer is null or
+.bP
+if the corresponding calls to \fBwaddch\fP return an error.
+.PP
+Functions with a "mv" prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,
+or if the window pointer is null.
 .SH NOTES
-Note that all of these routines except \fBwaddstr\fR and \fBwaddnstr\fR may be
-macros.
