I don't know if there is any interest in X/Open pread, pwrite calls. Essentially, they implement atomic seek/write and atomic seek/read calls. They are more useful in threaded apps where you would need a file lock between a seek/write or seek/read, but even in single threaded apps can allow you to avoid a syscall. Attached is an implementation. If there is interest, and if the implementation meets with approval, I'll submit a PR. Or, perhaps someone would want to commit it directly. I welcome any comments.
