BIO_janus_dtls_filter()

BIO_METHOD* BIO_janus_dtls_filter

(

void

)

OpenSSL BIO filter for fragmentation constructor.

janus_dtls_bio_filter_ctrl()

long janus_dtls_bio_filter_ctrl	(	BIO *	h,
		int	cmd,
		long	arg1,
		void *	arg2
	)

janus_dtls_bio_filter_free()

int janus_dtls_bio_filter_free

(

BIO *

data

)

janus_dtls_bio_filter_init()

int janus_dtls_bio_filter_init

(

void

)

OpenSSL BIO filter for fragmentation initialization.

janus_dtls_bio_filter_new()

int janus_dtls_bio_filter_new

(

BIO *

h

)

janus_dtls_bio_filter_set_mtu()

void janus_dtls_bio_filter_set_mtu

(

int

start_mtu

)

Set the MTU for the BIO filter.

Note

The default starting MTU is 1472, in case fragmentation is needed the OpenSSL DTLS stack automatically decreases it. That said, if you know for sure the MTU in the network Janus is deployed in is smaller than that, it makes sense to configure an according value to start from

Parameters

start_mtu

The MTU to start from (1472 by default)

janus_dtls_bio_filter_write()

int janus_dtls_bio_filter_write	(	BIO *	h,
		const char *	buf,
		int	num
	)
