The thing is ANY processing is inherently going to be racy, at least some of the time. The way to find out of part of a file is locked, is to try to take the lock yourself (LOCK_NB as an argument to flock may be useful here), if you get it then it was not held, and if your attempt fails then the lock is held by something else. ANYTHING else is going to give you inherently out of date information that may change from under you. You really need to find another way to do whatever it is you are really trying to do, why does a third party need to know which locks are held?
