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. SEE ALSO coredump_write(9) NetBSD 8.0 December 24, 2005 NetBSD 8.0
