1:07:43elxenoaizd Is there a standard / portable way in C to get a FILE* to a block / region in memory? In Linux there's fmemopen but I can't seem to find an equivalent in Windows. Internet seems to suggest MapViewOfFile but I don't think that is it, I don't want a memory mapped file, just FILE* to a memory region. Does such a thing exist or am I looking at this the wrong way?

1:09:38elxenoaizd Why is the preprocessor able to convert a parameter to a string via the # symbol, but not the other way around, i.e. string stripping, taking the inner value of the string and pasting it? My guess is that it's because this would not make it possible for the macro to be determined at compile time since we can pass it arbitrary strings?

1:12:29elxenoaizd Metaprogramming question: Let's say I want to have a generic dynamic list (resizable array) in my game library. Void-pointers and macros are two ways of approaching this; another is generating the code for the unique list types I want. Is this what you mean when you say "I write C programs that spit out C programs"? If so, can we do this generation at compile-time (like we can do in jai) or are we forced to write and run an executable that does the generation for us?

1:13:29CaptainKraft With respect to composition: I have a Player struct that has various other structs to represent what the player is composed of. One could be the Object struct which is added to any entity in the game that I want to behave like an object. Then I create functions that run on objects such as objectMove(Object *obj) so that anything that I want to move in the game would simply have an Object struct within it
