Controlling Seed to multi langauge verification environment

Hi

   I working on a multi language environment (UVM + C++)for an IP verification. I am new to C++. We are using a C++ model in our verification environment. We are precompiling the C++ model and call the C++ model through A DPI function. srand() function is called to generate random value in C++ file. We can control seed to UVM with -seed or -svseed irun command line option. Does C++ also use seed to generate its variables. If it does how can we control seed from irun command line?

    Hi Stephen

           Thanks for your reply again and also for the detailed explanation :)  The DUT model in C++ i received from another team member so i am not sure why he used srand function in it. Will confirm with him about it. As you suggested will try to do all randomization in SV. Thanks again for you time and response.
