core(4)                        DG/UX R4.11MU05                       core(4)


NAME
       core - a core image file

DESCRIPTION
       The system writes out a core image of a terminated process when any
       of several exceptions occur.  The system acknowledges an exception by
       generating a signal for the process that encountered the exception.
       If the signal is ignored or not handled, it causes the process to
       terminate and dump core.  See the header file sys/signal.h(2) for a
       list of the signals that terminate the receiving process and cause
       core files to be produced.

       The core image is called core and is written, if possible, in the
       process's working directory; normal access controls apply.  A process
       with an effective user id different from the real user id will not
       produce a core image.

       You can read a core file with one of the supplied debugging tools:
       mxdb or dbx.  See the man pages of these tools for more information
       on core file debugging.
