They did a strange reorg of the API docs at one point. Not only does it now have functions split by A/W (mostly unnecessarily), it also groups them by header file instead of feature reference, which is kind of annoying. It used to be just that the function doc would note at the bottom if A/W variants were present and they were grouped under Functions in the feature/subsystem area of the docs tree.

Yeah, that new content management system is awful too -- it doesn't grok preprocessor stuff at all, so sometimes you get nonsensical struct definitions, kernel-mode structs instead of user-mode structs, etc.
