Function Documentation

int get_netif_info	(	const char *	net_if,
		unsigned *	ip_addr,
		char **	ip_addr_text,
		u8	mac[ETH_ALEN],
		char **	mac_addr_text
	)

Get hw and IP addresses for network device.

Parameters:

	net_if	Selected network interface name
	ip_addr	Buffer for returning IP address in network byte order
	ip_addr_text	Buffer for returning a pointer to allocated IP address text
	mac	Buffer for returning MAC address
	mac_addr_text	Buffer for returning allocated MAC address text

Returns:

0 on success, -1 on failure

Here is the call graph for this function:

struct subscription* subscription_start	(	struct upnp_wps_device_sm *	sm,
		const char *	callback_urls
	)			[read]

Remember a UPnP control point to send events to.

Parameters:

	sm	WPS UPnP state machine from upnp_wps_device_init()
	callback_urls	Callback URLs

Returns:

NULL on error, or pointer to new subscription structure.

Definition at line 745 of file wps_upnp.c.

Here is the call graph for this function:

void upnp_wps_device_deinit

(

struct upnp_wps_device_sm *

sm

)

Deinitialize WPS UPnP.

Parameters:

sm

WPS UPnP state machine from upnp_wps_device_init()

Definition at line 1101 of file wps_upnp.c.

Here is the call graph for this function:

struct upnp_wps_device_sm* upnp_wps_device_init	(	struct upnp_wps_device_ctx *	ctx,
		struct wps_context *	wps,
		void *	priv
	)			[read]

Initialize WPS UPnP.

Parameters:

	ctx	callback table; we must eventually free it
	wps	Pointer to longterm WPS context
	priv	External context data that will be used in callbacks

Returns:

WPS UPnP state or NULL on failure

Definition at line 1126 of file wps_upnp.c.

Here is the call graph for this function:

int upnp_wps_device_send_wlan_event	(	struct upnp_wps_device_sm *	sm,
		const u8	from_mac_addr[ETH_ALEN],
		enum upnp_wps_wlanevent_type	ev_type,
		const struct wpabuf *	msg
	)

Event notification.

Parameters:

	sm	WPS UPnP state machine from upnp_wps_device_init()
	from_mac_addr	Source (Enrollee) MAC address for the event
	ev_type	Event type
	msg	Event data

Returns:

0 on success, -1 on failure

Tell external Registrars (UPnP control points) that something happened. In particular, events include WPS messages from clients that are proxied to external Registrars.

Parameters:

	sm	WPS UPnP state machine from upnp_wps_device_init()
	net_if	Selected network interface name

Returns:

0 on success, -1 on failure

Definition at line 1039 of file wps_upnp.c.

Definition at line 997 of file wps_upnp.c.

Here is the call graph for this function:

int upnp_wps_subscribers

(

struct upnp_wps_device_sm *

sm

)

Check whether there are any event subscribers.

Parameters:
