To: Davido,

Nice!!!, I had no clue for that trap. Well I found that by closing the file the unlock happens automatically File Locking.

So regarding the reason that I am using flock on reading. I was planning to possible extend my conf.ini file by writing into it while some processes might reading. I just wanted to compare the process with all having this extra feature (flock), before I conclude which one to use.

Thank you for pointing out all this information, beginners like me learn so much.
