I have no fpc available at the moment. However, you can build yourself
the fcl-res documentation (run makehtml.sh) in xml directory, inside fcl-res
directory. There are examples for groupiconresource too.

In general, if you need to use resources at runtime you should check Microsoft
documentation about resources. If you need to manipulate resources (e.g. read
a .ico file in a series of resources, or the other way around) use fcl-res.
