| * Used to declare a structure unaligned, so that the C compiler, |

| * This is required because there is no guarantee that the packet |
| * data we get from libpcap/WinPcap is properly aligned. |
| * |
| * This assumes that, for all compilers that support __attribute__: |
| * |
| * 1) they support __attribute__((packed)); |
| * |
| * 2) for all instruction set architectures requiring strict |
| * alignment, declaring a structure with that attribute |
| * causes the compiler to generate code that handles |
| * misaligned 2-byte, 4-byte, and 8-byte integral |
| * quantities. |
| * |
| * It does not (yet) handle compilers where you can get the compiler |
| * to generate code of that sort by some other means. |
| * |
| * This is required in order to, for example, keep the compiler from |
| * generating, for |
| * |
| * if (bp->bp_htype == 1 && bp->bp_hlen == 6 && bp->bp_op == BOOTPREQUEST) { |
| * |
| * in print-bootp.c, code that loads the first 4-byte word of a |
| * "struct bootp", masking out the bp_hops field, and comparing the result |
| * against 0x01010600. |
| * |
| * Note: this also requires that padding be put into the structure, |
| * at least for compilers where it's implemented as __attribute__((packed)). |
