.Dd December 24, 2005 .Dt CPU_COREDUMP 9 .Os .Sh NAME .Nm cpu_coredump .Nd machine-dependent process core dump interface .Sh SYNOPSIS n sys/signalvar.h .Ft int .Fn cpu_coredump "struct lwp *l" "void *iocookie" "struct core *chdr" .Ft int .Fn cpu_coredump32 "struct lwp *l" "void *iocookie" "struct core32 *chdr" .Sh DESCRIPTION .Fn 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. .Fa l is the lwp structure of the thread being dumped. .Fa iocookie is an opaque pointer to be passed to .Fn coredump_write . Information about the machine-dependent header sections are returned in .Fa chdr .

p .Fn cpu_coredump returns 0 on success and an appropriate error code on failure. .Sh CODE REFERENCES Process core dumps are initiated within the file
