Let's ignore for a moment whether the limit is INT_MAX or SIZE_MAX.
fgetln does have a platform specific limit due to the amount of memory.
Imagine that fgetln uses a very smart lookup algorithm in the backend.
It can be imagined that it might know the length of the line without
reading it to memory completely or that it is using a compressed buffer
or whatever. For this reason documenting that this can result in an
error is a good way anyway.
I will fix the size_t vs int, but that's a separate question.
