645 * NetBSD-specific core file information.
647 * NetBSD ELF core files use notes to provide information about
648 * the process's state. The note name is "NetBSD-CORE" for
649 * information that is global to the process, and "NetBSD-CORE@nn",
650 * where "nn" is the lwpid of the LWP that the information belongs
651 * to (such as register state).
653 * We use the following note identifiers:
655 * ELF_NOTE_NETBSD_CORE_PROCINFO
656 * Note is a "netbsd_elfcore_procinfo" structure.
658 * We also use ptrace(2) request numbers (the ones that exist in
659 * machine-dependent space) to identify register info notes. The
660 * info in such notes is in the same format that ptrace(2) would
661 * export that information.
663 * Please try to keep the members of this structure nicely aligned,
664 * and if you add elements, add them to the end and bump the version.
