NAME
       core - format of core image file

DESCRIPTION
       UNIX  writes  out  a  core image of a terminated process when any of various errors occur.  See signal(2) for the list of reasons; the most
       common are memory violations, illegal instructions, bus errors, and user-generated quit signals.  The core image is called  `core'  and	is
       written in the process's working directory (provided it can be; normal access controls apply).

       The  first  1024  bytes of the core image are a copy of the system's per-user data for the process, including the registers as they were at
       the time of the fault; see the system listings for the format of this area.  The remainder represents the actual  contents  of  the  user's
       core  area  when  the  core  image  was written.  If the text segment is write-protected and shared, it is not dumped; otherwise the entire
       address space is dumped.

       In general the debugger adb(1) is sufficient to deal with core images.
