generally we try to avoid calling the public versions of libc functions from one another. The preferred pattern if you need the same functionality in multiple places is to create a shared helper and call that helper (see `str_to_integer.h` as an example). For `fcntl` I'd recommend putting this in `__support/OSUtil/`, and for `fseek` you can just call `FILE->seek` to get the same functionality.
