+Functions with a \*(``mv\*('' prefix first perform a cursor movement using
+\fBwmove\fP, and return an error if the position is outside the window,

 .SH NOTES
 Note that \fBgetstr\fR, \fBmvgetstr\fR, and \fBmvwgetstr\fR may be macros.
 .SH PORTABILITY
 These functions are described in the XSI Curses standard, Issue 4.
 They read single-byte characters only.
 The standard does not define any error conditions.
-This implementation returns ERR if the window pointer is null,

 SVr3 and early SVr4 curses implementations did not reject function keys;

 The functions \fBgetnstr\fR, \fBmvgetnstr\fR, and \fBmvwgetnstr\fR were
 present but not documented in SVr4.
