If a program is linked with GNU ld using the --build-id option, how

I've never done it but maybe a place to start is use the elfreader unit
in fcl-res to open ParamStr(0) and read the data from the
.note.gnu.build-id section.
Thanks, I'll take a look. I'm looking for something that I can put as a
"magic number" at the bottom of some shared memory, and the build-id is
ideal since it can be set to a fixed value during debugging.
