Member types

Member type	Definition
result_type	The integral type generated by the engine. Results are undefined if this is not an unsigned integral type.

Member variables

constexpr size_t shift_size [static]	(public static member constant)
constexpr size_t mask_bits [static]	(public static member constant)

Member functions

Construction and Seeding
(constructor)	constructs the engine (public member function)
seed	sets the current state of the engine (public member function)
Generation
operator()	advances the engine's state and returns the generated value (public member function)
discard	advances the engine's state by a specified amount (public member function)
Characteristics
min [static]	gets the smallest possible value in the output range (public static member function)
max [static]	gets the largest possible value in the output range (public static member function)

Non-member functions

operator== operator!=	compares the internal states of two pseudo-random number engines (function)
operator<< operator>>	performs stream input and output on pseudo-random number engine (function)
