Function Documentation

gateroute()

int gateroute	(	unsigned int	command,
		struct rtmptab *	rtmp
	)

looproute()

int looproute	(	struct interface *	iface,
		unsigned int	cmd
	)

newrt()

struct rtmptab * newrt

(

const struct interface *

iface

)

rtmp_addinuse()

static void rtmp_addinuse ( struct rtmptab *  rtmp )

static

Add rtmp to the per-interface in-use table.

Note

No verification is done...

rtmp_config()

static int rtmp_config ( struct rtmp_head *  rh, struct interface *  iface  )

static

Complete configuration for phase 1 interface using RTMP information.

rtmp_copyzones()

static int rtmp_copyzones ( struct rtmptab *  to, struct rtmptab *  from  )

static

Change the zone mapping to replace "from" with "to".

Note

This code assumes the consistency of both the route -> zone map and the zone -> route map. This is probably a bad idea. How can we insure that the data is good at this point? What do we do if we get several copies of a route in an RTMP packet?

rtmp_delinuse()

static void rtmp_delinuse ( struct rtmptab *  rtmp )

static

Delete rtmp from the per-interface in-use table, remove all zone references, and remove the route from the kernel.

rtmp_delzonemap()

void rtmp_delzonemap

(

struct rtmptab *

rtmp

)

rtmp_free()

void rtmp_free

(

struct rtmptab *

rtmp

)

Remove rtmp from the in-use table and the per-gate table. Free any associated space.

rtmp_new()

static int rtmp_new ( struct rtmptab *  rtmp )

static

rtmp_packet()

int rtmp_packet	(	struct atport *	ap,
		struct sockaddr_at *	from,
		char *	data,
		int	len
	)

rtmp_replace()

int rtmp_replace

(

struct rtmptab **

replace_ptr

)

Find a replacement for the structure pointed to by "replace_ptr".

Returns

If we can't find a replacement, return 1.

If we do find a replacement, return 0.

If we encounter an error, return -1.

rtmp_request()

int rtmp_request

(

struct interface *

iface

)
