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.
CODE REFERENCES
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.
