[ECOS] cyg_io_lookup () and handles

[Trenton D. Adams]

Ok, this is fine.  But does this mean I'm going to have to go looking
through the sources just to find what handles I can use?  After all,
isn't a handle just an unsigned integer identifier?  Or is it just the
"/dev/ser1" kind of thing?  In which case I could call mine
"/dev/mySuperWirelessDeviceThingy"! LOL

The developer is in control of the code they are using so it's up to
them to only have unique names in their sources :-). Just name new ones
unambiguously, preferably based around what is distinctive about their
driver.

There's no standard as such because the only way to make names truly
unique is to have a central registration authority, and that's just too
much overhead for something small like this :-).
