xmpp_ctx_t *

ctx

)

Create new xmpp_rand_t object.

Parameters

ctx	A Strophe context object

xmpp_rand_free()

void xmpp_rand_free	(	xmpp_ctx_t *	ctx,
		xmpp_rand_t *	rand
	)

Destroy an xmpp_rand_t object.

Parameters

ctx	A Strophe context object

xmpp_rand()

int xmpp_rand

Generate random integer.

Analogue of rand(3).

xmpp_rand_bytes()

void xmpp_rand_bytes	(	xmpp_rand_t *	rand,
		unsigned char *	output,
		size_t	len
	)

Generate random bytes.

Generates len bytes and stores them to the output buffer.

xmpp_rand_nonce()

void xmpp_rand_nonce	(	xmpp_rand_t *	rand,
		char *	output,
		size_t	len
	)

Generate a nonce that is printable randomized string.

This function doesn't allocate memory and doesn't fail.

Parameters

output	A buffer where a NULL-terminated string will be placed. The string will contain len-1 printable symbols.
len	Number of bytes reserved for the output string, including end of line '\0'.
