uint32_t(*	get_u32 )(void *)
	Callback to get 4 unsigned bytes from the underlying generator.
bool(*	fixup_state )(void *)

char	state []
	flexible length array so that the generator's state can be stored in the same allocation

Detailed Description

A PseudoRandom Number Generator.

This is a generic representation, generally to be heap-allocated by one of the functions in this file. That means the prng state is stored in the flexible length array in the same allocation, decreasing memory fragmentation and making copying prng state easier.

Field Documentation

fixup_state

bool(* cr8r_prng::fixup_state) (void *)

Called after "randomizing" the state.

Typically the state is initialized using splitmix and then this function is called to ensure it is good.
