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 sec- tions 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.
