Method lrs::file::File::lock_exclusive

Tries to lock this file exclusively.

Syntax

impl File {
    fn lock_exclusive(&self) -> Result<(), Errno>

Remarks

Note that this locking is voluntary. Other programs can continue to modify the file even if you hold a lock. All programs must cooperate and use the locking functions to get reliable locking.
