# NAME

coredump_write — common coredump write routine

# SYNOPSIS

#include <sys/signalvar.h>

int
coredump_write(void *iocookie, enum uio_seg segflg, const void *data, size_t len);

# DESCRIPTION

coredump_write() is used by both machine-dependent and machine-independent components to write information to a coredump. iocookie is an opaque pointer that was supplied to the caller of coredump_write(). segflg indicates where the data is located, system space or user space. data points to the information to be written to the coredump. len is the amount of data to be written.

coredump_write() returns 0 on success and an appropriate error code on failure.
