Function Documentation

int add_ssdp_network

(

const char *

net_if

)

Add routing entry for SSDP.

Parameters:

net_if

Selected network interface name

Returns:

0 on success, -1 on failure

This function assures that the multicast address will be properly handled by Linux networking code (by a modification to routing tables). This must be done per network interface. It really only needs to be done once after booting up, but it does not hurt to call this more frequently "to be safe".

Here is the call graph for this function:

int advertisement_state_machine_start

(

struct upnp_wps_device_sm *

sm

)

Start SSDP advertisements.

Parameters:

sm

WPS UPnP state machine from upnp_wps_device_init()

Returns:

0 on success, -1 on failure

Definition at line 350 of file wps_upnp_ssdp.c.

Here is the call graph for this function:

void advertisement_state_machine_stop	(	struct upnp_wps_device_sm *	sm,
		int	send_byebye
	)

Stop SSDP advertisements.

Parameters:

	sm	WPS UPnP state machine from upnp_wps_device_init()
	send_byebye	Send byebye advertisement messages immediately

Definition at line 236 of file wps_upnp_ssdp.c.

Here is the call graph for this function:

void msearchreply_state_machine_stop

(

struct advertisement_state_machine *

a

)

Stop M-SEARCH reply state machine.

Parameters:

a

Selected advertisement/reply state

Here is the call graph for this function:

int ssdp_listener_start

(

struct upnp_wps_device_sm *

)

Set up for receiving discovery (UDP) packets.

Parameters:

sm

WPS UPnP state machine from upnp_wps_device_init()

Returns:

0 on success, -1 on failure

The SSDP listener is stopped by calling ssdp_listener_stop().

Definition at line 809 of file wps_upnp_ssdp.c.

Here is the call graph for this function:

void ssdp_listener_stop

struct upnp_wps_device_sm *

sm

)

Stop SSDP listered.

Parameters:

sm

WPS UPnP state machine from upnp_wps_device_init()

This function stops the SSDP listener that was started by calling ssdp_listener_start().

Definition at line 701 of file wps_upnp_ssdp.c.

Here is the call graph for this function:

int ssdp_open_multicast

(

struct upnp_wps_device_sm *

)

Open socket for sending multicast SSDP messages.

Parameters:

sm

WPS UPnP state machine from upnp_wps_device_init()

Returns:

0 on success, -1 on failure
