NAME
cpu_coredump —
machine-dependent process core dump
interface
SYNOPSIS
#include
<sys/signalvar.h>
int
cpu_coredump(struct
lwp *l, void
*iocookie, struct core
*chdr);
int
cpu_coredump32(struct
lwp *l, void
*iocookie, struct core32
*chdr);
DESCRIPTION
cpu_coredump()
is the machine-dependent interface invoked by machine-independent code to dump
the machine-dependent header information at the start of a process core dump.
The header information primarily consists of the CPU and floating-point
registers. l is the lwp structure of the thread being
dumped. iocookie is an opaque pointer to be passed to
coredump_write().
Information about the machine-dependent header sections are returned in
chdr.
cpu_coredump()
returns 0 on success and an appropriate error code on failure.

Process core dumps are initiated within the file sys/kern/kern_sig.c. Process core dumps for ELF NetBSD binaries are performed within the files sys/kern/core_elf32.c or sys/kern/core_elf64.c. Process core dumps for other NetBSD binaries are performed within the file sys/kern/core_netbsd.c.
