Hi, I have two tasks 'Read' and 'Write' which reads and writes on a file "abc.txt" respectively.
Now I need to restrict the Write operation on the file while Read is going on, But can allow two Reads at a time.
ie. two Reads can happen simultaneously, but Write can't happen at Read is going on.

I can do this by using Mutex lock which can lock the file at the start of Read and release after completion of Read, But by doing this the second Read will also won't get access to the file.

Can anybody have idea, how to handle this?

Thanks in advance.

Cheers
