Does driver need to deal with synchronization for multiple write access ? RRS feed

  • Question

  • Hi Experts:

    If a driver deals with file reading/writing, does it need to synchronize the operations using mutex or something like that ? Especially for the write access ?  If not needed, who is taking care of the multiple write requests which are coming at the same time?

    Thanks in advance.

  • You need to handle this in the driver, that is one of the great strengths of KMDF, it provides mechanisms for doing this simply without requiring any signficant work.
