Non-member functions

operator==operator!=

operator<<operator>>

void discard( unsigned long long z );		(since C++11)

Advances the internal state by z times. Equivalent to calling operator() z times and discarding the result

Parameters

z

-

integer value specifying the number of times to advance the state by

Return value

(none)

Notes

For some engines, "fast jump" algorithms are known, which advance the state by many steps (order of millions) without calculating intermediate state transitions, although not necessarily in constant time.

operator()

advances the engine's state and returns the generated value (public member function)
