CPU_COREDUMP(9)            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.
