Detailed Description

Internal API for generating pseudo random numbers.

Function Documentation

coap_prng_init_lkd()

void coap_prng_init_lkd

(

unsigned int

seed

)

Seeds the default random number generation function with the given seed.

The default random number generation function will use getrandom() if available, ignoring the seed.

Parameters

seed	The seed for the pseudo random number generator.

Here is the caller graph for this function:

coap_prng_lkd()

int coap_prng_lkd	(	void *	buf,
		size_t	len
	)

Fills buf with len random bytes using the default pseudo random number generator.

The default PRNG can be changed with coap_set_prng(). This function returns 1 when len random bytes have been written to buf, zero otherwise.

Parameters

buf	The buffer to fill with random bytes.
len	The number of random bytes to write into buf.

Returns

1 on success, 0 otherwise.
