Quickly find whether a value is present in a C array?
... much faster than a linear search of 256 or 1024 values.
I've written some Python code to find reasonable hash functions.
Binary search
If you sort your array of 256 "valid" values, then you can do a binary search, rather than a linear search. That means you should be able to search 256-entry table ...

What exactly is a reentrant function?
....
There are many programming systems out there: Ocaml is one, and I think Python as well, which have lots of non-reentrant code in them, but which uses a global lock to interleave thread acesss. These systems are not re-entrant and they're not thread-safe or concurrent-safe, they operate safely sim...
