Hello! I'm writing a Qt/c++ program that should write and read data on a file, while another process does the same. What file format should I use to prevent conflicts?

I like the solution of the single process, thank you very much!

if program A used what it reads to write back and program B writes in the meanwhile A's work won't be ok.

transactions solve this.
