exist and the program is running in a window, the current window size

In System V Release 4, \fBset_curterm\fR has an \fBint\fR return type and
returns \fBOK\fR or \fBERR\fR. We have chosen to implement the XSI Curses
semantics.
So though it is documented as a terminfo function,
\fBmvcur\fR is really a curses function which is not well specified.
