Function Documentation

lws_xos_init()

LWS_VISIBLE LWS_EXTERN void lws_xos_init	(	struct lws_xos *	xos,
		uint64_t	seed
	)

lws_xos_init() - seed xoshiro256 PRNG

Parameters

xos	the prng state object to initialize
seed	the 64-bit seed

Initialize PRNG \xos with the starting state represented by seed

lws_xos()

LWS_VISIBLE LWS_EXTERN uint64_t LWS_WARN_UNUSED_RESULT lws_xos

(

struct lws_xos *

xos

)

lws_xos() - get next xoshiro256 PRNG result and update state

Parameters

xos	the PRNG state to use

Returns next 64-bit PRNG result. These are cheap to get, quite a white noise sequence, and completely deterministic according to the seed it was initialized with.

lws_xos_percent()

LWS_VISIBLE LWS_EXTERN int LWS_WARN_UNUSED_RESULT lws_xos_percent	(	struct lws_xos *	xos,
		int	percent
	)

lws_xos_percent() - return 1 a given percent of the time on average

Parameters

xos	the PRNG state to use
percent	chance in 100 of returning 1

Returns 1 if next random % 100 is < percent, such that 100 always returns 1, 0 never returns 1, and the chance linearly scales inbetween
