941 * dp = (u_int32_t *)&rp->rm_reply.rp_acpt.ar_verf
942 * On the wire, the rp_acpt field starts immediately after
943 * the (32 bit) rp_stat field. However, rp_acpt (which is a
944 * "struct accepted_reply") contains a "struct opaque_auth",
945 * whose internal representation contains a pointer, so on a
946 * 64-bit machine the compiler inserts 32 bits of padding
947 * before rp->rm_reply.rp_acpt.ar_verf. So, we cannot use
948 * the internal representation to parse the on-the-wire
949 * representation. Instead, we skip past the rp_stat field,
950 * which is an "enum" and so occupies one 32-bit word.
952 dp = ((const u_int32_t *)&rp->rm_reply) + 1;
954 len = EXTRACT_32BITS(&dp[1]);
958 * skip past the ar_verf credentials.
960 dp += (len + (2*sizeof(u_int32_t) + 3)) / sizeof(u_int32_t);
964 * now we can check the ar_stat field
