Detailed Description

API functions for gerating pseudo random numbers.

Macro Definition Documentation

prng

#define prng	(		Buf,
			Length
	)

Fills Buf with Length bytes of random data.

Definition at line 112 of file prng.h.

prng_init

#define prng_init

(

Value

)

Called to set the PRNG seed.

You may want to re-define this to allow for a better PRNG.

Function Documentation

coap_prng_impl()

COAP_STATIC_INLINE int coap_prng_impl	(	unsigned char *	buf,
		size_t	len
	)

Fills buf with len random bytes.

This is the default implementation for prng(). You might want to change prng() to use a better PRNG on your specific platform.
