/*
44
 * Macros used for conversion to/from xdr representation by nfs...
45
 * These use the MACHINE DEPENDENT routines ntohl, htonl
46
 * As defined by "XDR: External Data Representation Standard" RFC1014
47
 *
48
 * To simplify the implementation, we use ntohl/htonl even on big-endian
49
 * machines, and count on them being `#define'd away.  Some of these
50
 * might be slightly more efficient as quad_t copies on a big-endian,
51
 * but we cannot count on their alignment anyway.
