std::seed_seq

class seed_seq;
Seed sequence
A seed sequence is an object that uses a sequence of integer values to produce a series of unsigned integer values with 32 significant bits that can be used to seed a pseudo-random generator engine.

The standard class seed_seq is an example of a seed sequence class. Objects of custom classes can be used to seed engines, provided they have the same members with at least their basic behavior.
