"namespacing" in C means prefixes on public symbols. Typically, they're two-part. First you have the project/company prefix, and then the ADT (abstract data type) prefix. So, eg. "foo_hash_" is a prefix from company/project "foo" and is a part of the "hash" ADT interface. As a consequence, C people like abbreviations. Which is fine in moderation. Private functions don't need the prefixes, of course. Public variables are a little problematic if you ever port to Windows (DLLs), so try to avoid them.
