rcheevos

rcheevos is a set of C code, or a library if you will, that tries to make it easier for emulators to interface with the RetroAchievements website services and provide achievements and leaderboards for their players.

rcheevos is not a complete solution in that it doesn't provide HTTP network connections or JSON parsing. The emulator has to implement that by itself, and pass the results down to rcheevos for processing.

Not all structures defined by rcheevos can be created via the public API, but are exposed to allow iteractions beyond just cretion, destruction, and testing, such as the ones required by UI code that helps creating them.

Finally, rcheevos does not allocate any memory or manage memory by itself. All structures that can be returned by it have a function that will determine the number of bytes needed to hold the structure, and another that will actually build the structure and that takes a caller-provided buffer to bake the structure. However, calls to **rc
