 .SH RETURN VALUE
 All of the functions return \fBERR\fR upon failure,
 or the number of characters actually read into the string.
+.PP
+X/Open defines no error conditions.
+In this implementation,
+if the window parameter is null or the str parameter is null,
+a zero is returned.
+.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 routines except \fBwinnstr\fR may be macros.
 .SH PORTABILITY
