According to your nick, you must have fresh kernel unpacked. Go to Documentation. read mandatory.txt . If you mean FILE*, well, FILE* is option. If you mean internal kernel structure - yes, but stable-api-nonsense.txt, so don't rely on it unless you are writing in-kernel code related to it in which case you look up in the source. Generally you have fcntl (read man) to get/set state of locking.
