Are you thinking of xdr_setpos? There is a cryptic warning about it
in 'man xdr'...
int xdr_setpos(XDR *xdrs, u_int pos)
A macro that invokes the set position routine associated with
the XDR stream xdrs. The pos argument is a position value obtained
from xdr_getpos(). This routine returns one if the XDR stream could
be repositioned, and zero otherwise.
Warning: it is difficult to reposition some types of XDR
streams, so this routine may fail with one type of stream and succeed
with another.
