Multi thread read / write

[Renejm]

I am exchanging information between two different strategies by writing the info to a file from the first strategy and reading the same infor from that file in the second strategy. Because NT is multi threading there is a change of conflict between reading and writing at the same time from the same file. Is there a way to prevent writing and reading at the same time, it should be sequential.

Kind regards,
Rene

You will need a mutex if you want to force sequential write before read, and have the writer signal the reader when it finishes writing.
