 All characters to the right of the cursor are shifted right,

+The functions with \fIn\fP as the last argument
+insert a leading substring of at most \fIn\fP \fBwchar_t\fP characters.
+If \fIn\fP is less than zero, the entire string is inserted
+(stopping on a L'\e0' character).

-If a character in \fIwstr\fR is a tab, newline, carriage return or
-backspace, the cursor is moved appropriately within the window.
-A newline also does a \fBclrtoeol\fR before moving.
-Tabs are considered to be at every eighth column.
-If a character in \fIwstr\fR is another control character,
-it is drawn in the \fB^\fR\fIX\fR notation.
-Calling \fBwin_wch\fR after adding a control character
-(and moving to it, if necessary)
-does not return the control character,
-but instead returns a character in the ^-representation
-of the control character.
+Special characters are handled as in \fBwadd_wch\fP(3X).
+.SH RETURN VALUE
+All functions return the integer \fBERR\fP upon failure and \fBOK\fP on success.
+.PP
+X/Open Curses does not specify any error conditions.
+This implementation returns an error

+if the \fIwin\fP parameter is null or

+if the \fIwstr\fP parameter is null or

+if the \fBwins_wch\fP function returns an error.
+.PP
+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP(3X), and return an error if the position is outside the window,
+or if the window pointer is null.

-.SH RETURN VALUES
-Upon successful completion, these functions return OK.
-Otherwise, they return ERR.
+.SH PORTABILITY
+These functions are described in the XSI Curses standard, Issue 4,
+which adds \fI\%const\fP qualifiers to the arguments.

 .PP
 .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.
+X/Open states that the entire string is inserted if \fIn\fP is less than 1.
+This is probably an error,
+because it is inconsistent with other functions,
+and differs from the X/Open implementation on Solaris.
