int
cpu_coredump32(
struct lwp *l
, void *iocookie
, struct core32 *chdr
)
)
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
.
