This is awkward and I apologize but I cannot review this PR. The taco dev has been very adamant about what their software license is, and it is incompatible with the GPL.

If this PR is just a couple lines that does something like

if (size of(memory file) == 0) {
    create_memory_file(MAX_MEMORY_FILE_SIZE)
}

then I can merge it if you can find the example to it in public documentation and use theirs instead. But I cannot pull code copied from taco without the original author's approval. (see taco issue number 2)

It's just a syscall. Nothing about it is specific to taco. just mentioned it as a futures reference to the related code from similar project. And this is c code which taco is CPP code, that's why we need to use sizeof (struct LinkedMem) compared to taco.

kinda my first PR. so i messed it up. help me Asher sempai :) i added 3 files instead of just the burrito_link file

I recommend using git restore to roll back the files you did not intend to submit and make a new commit that reverts them. After submitting you can use git restore again to roll back the roll back locally so you still have your changes on your machine.

it feels big because of formatting changes, but i tried my best to stick to the reference docs of microsoft. checked that it works.
