I'm not 100% sure of this in Linux, but flock(2) is an advisory lock, so 
that anyone can modify the file regardless of the lock state. 

I strongly recommend that you use fcntl(2) as your lock mechanism as it is=
 
semanticly and syntacticly standard across platforms. It locks across NFS.=
 
You can also lock a portion of a file.
