elf core dump files

[tms2 at mail.ptd.net (T.M. Sommers)]

I am trying to write a little program to get some information from core
dump files.  I do not understand, however, what is in each of the
loadable segments in the core dump, and how those segments correlate to
the segments in the executable file.  For one thing, there are more
loadable segments in the core dump than in the executable.

Could someone give me a push in the right direction?  Thanks.
