CPU_COREDUMP(9) FreeBSD Kernel Developer's Manual CPU_COREDUMP(9)
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.
