.SH DESCRIPTION
-These routines copy the array of complex characters \fIwchstr\fR
-into the window image structure at and after the current cursor position.
-The four routines with \fIn\fR as the last
-argument copy at most \fIn\fR elements, but no more than will fit on the line.
+These functions copy the (null-terminated)
+array of complex characters \fIwchstr\fR
+into the window image structure
+starting at the current cursor position.
+The four functions with \fIn\fR as the last
+argument copy at most \fIn\fR elements,
+but no more than will fit on the line.
If \fBn\fR=\fB\-1\fR then the whole array is copied,
to the maximum number of characters that will fit on the line.
.PP
The window cursor is \fInot\fR advanced.
-These routines work faster than \fBwaddnstr\fR.
-On the other hand, they do not perform checking
+These functions work faster than \fBwaddnstr\fR.
+On the other hand:
+.bP
+they do not perform checking
(such as for the newline, backspace, or carriage return characters),
+.bP
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,
+.bP
+they do not expand other control characters to ^-escapes, and
+.bP
+they truncate the string if it crosses the right margin,
rather than wrapping it around to the new line.
.PP
-These routines end successfully
+These functions end successfully
on encountering a null \fIcchar_t\fR, 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.
-.SH NOTES
-All functions except \fBwadd_wchnstr\fR may be macros.
-.SH RETURN VALUES
-All routines return the integer \fBERR\fR upon failure and \fBOK\fR on success.
+.SH RETURN VALUE
+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
+if the window pointer is null.
.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
+All functions except \fBwadd_wchnstr\fR may be macros.
.SH PORTABILITY
