 All of the functions return \fBERR\fR upon failure,
 or the number of characters actually read into the string.
+.PP
+X/Open Curses defines no error conditions.
+In this implementation:
+.bP
+If the \fIwin\fP parameter is null, an error is returned,
+.bP
+If the \fIchstr\fP parameter is null, an error is returned,

+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
-The XSI Curses
-error conditions \fBEILSEQ\fR and \fBEILOVERFLOW\fR associated with
