COREDUMP_WRITE(9)      NetBSD Kernel Developer's Manual      COREDUMP_WRITE(9)

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-indepen-
     dent 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.
