The utility functions are kind of spread throughout, but most of them are defined as part of what Valve calls the 'Tier 1" library which contains, more or less, a custom implementation of the entire STL which has been fully integrated into the engine with datamap support and all.
Tier 1 tends to be a little more explicit about the underlying data type for a given container than STL, and has separate classses for hashes, red-black trees, and maps, as well as more specialized classes such as string maps, sorted vectors, dictionaries, and 2way lookup maps (handy for collision detection and related problems). The full list is in src/public/tier1 in the ep1 code, but I think the directory structure might have changed in the OB SDK. All of these classes are typically prepended with "CUTL". The code for them is *generally* well documented, but might be a little rough on someone who hadn't studied computer science at all. More generally, there are also a number of UTIL_ functions spread throughout the code. The /vast /majority of them however are defined in either game_shared/util_shared.h for shared functions, cl_dll/cdll_util.h for client only, or dll/utils.h for server only I would also advise a quick read through of math.h and dbg.h just so you know what options you have built into the engine. There are also extensive libraries for everything basic memory management to, in OB at least, parallel processing, and while they're all useful to know about if you need them, I wouldn't really go too far into them if you're just starting out. Good luck getting it all on the wiki.
