public member function
<random>
std::discard_block_engine::discardvoid discard (unsigned long long z);
Advance internal state
Advances the internal state by z notches, as if operator() was called z times, but without generating any numbers in the process.The effects on the state sequence are the same as if the transition algorithm was applied as many times as notches advanced on subsequent elements.
