     2   * Compile and run this as a C program to get the kinfo_proc offsets
     3   * for your architecture.
     4   * While FreeBSD works hard at binary-compatibility within an ABI, various
     5   * we can't say for sure that these are right for _all_ use on a hardware
     6   * platform.  The LP64 ifdef affects the offsets considerably.
     7   *
     8   * We use these offsets in hardware-specific files for FreeBSD, to avoid a cgo
     9   * compilation-time dependency, allowing us to cross-compile for FreeBSD from
    10   * other hardware platforms, letting us distribute binaries for FreeBSD.
