Detailed Description

EthInterface class.

Common interface that is shared between ethernet hardware.

Definition at line 30 of file EthInterface.h.

Member Typedef Documentation

typedef mbed::Callback<void (nsapi_error_t result, SocketAddress *address) hostbyname_cb_t) [inherited]

Hostname translation callback (asynchronous)

Callback will be called after DNS resolution completes or a failure occurs.

Callback should not take more than 10ms to execute, otherwise it might prevent underlying thread processing. A portable user of the callback should not make calls to network operations due to stack size limitations. The callback should not perform expensive operations such as socket recv/send calls or blocking operations.

Parameters:

status	0 on success, negative error code on failure
address	On success, destination for the host SocketAddress

Definition at line 180 of file NetworkInterface.h.

Member Function Documentation

nsapi_error_t add_dns_server ( const SocketAddress & address ) [virtual, inherited]

Add a domain name server to list of servers to query.

Parameters:

address Destination for the host address

Returns:: 0 on success, negative error code on failure

Definition at line 73 of file NetworkInterface.cpp.

void attach ( mbed::Callback< void(nsapi_event_t, intptr_t)> status_cb ) [virtual, inherited]

Register callback for status reporting.

The specified status callback function will be called on status changes on the network. The parameters on the callback are the event type and event-type dependent reason parameter.

Parameters:

status_cb The callback for status changes

Definition at line 78 of file NetworkInterface.cpp.

virtual CellularBase* cellularBase ( ) [virtual, inherited]

Dynamic downcast to a CellularBase.

Definition at line 265 of file NetworkInterface.h.

virtual nsapi_error_t connect ( ) [pure virtual, inherited]

Start the interface.

Returns:: 0 on success, negative error code on failure

virtual nsapi_error_t disconnect ( ) [pure virtual, inherited]

Stop the interface.

Returns:: 0 on success, negative error code on failure

virtual EMACInterface* emacInterface ( ) [virtual, inherited]

Dynamic downcast to an EMACInterface.

Definition at line 271 of file NetworkInterface.h.

nsapi_connection_status_t get_connection_status ( ) const [virtual, inherited]

Get the connection status.

Returns:: The connection status according to ConnectionStatusType

Definition at line 82 of file NetworkInterface.cpp.

MBED_WEAK EthInterface * get_default_instance ( ) [static]

Get the default Ethernet interface.

This is provided as a weak method so applications can override. Default behaviour is to get the target's default interface, if any.

Returns:: pointer to interface, if any

Definition at line 28 of file NetworkInterfaceDefaults.cpp.

const char * get_gateway ( ) [virtual, inherited]

Get the local gateway.

Returns:: Null-terminated representation of the local gateway or null if no network mask has been received

Definition at line 38 of file NetworkInterface.cpp.

const char * get_ip_address ( ) [virtual, inherited]

Get the local IP address.

Returns:: Null-terminated representation of the local IP address or null if no IP address has been received

Definition at line 28 of file NetworkInterface.cpp.

const char * get_mac_address ( ) [virtual, inherited]

Get the local MAC address.

Provided MAC address is intended for info or debug purposes and may not be provided if the underlying network interface does not provide a MAC address

Returns:: Null-terminated representation of the local MAC address or null if no MAC address is available

Definition at line 23 of file NetworkInterface.cpp.

const char * get_netmask ( ) [virtual, inherited]

Get the local network mask.

Returns:: Null-terminated representation of the local network mask or null if no network mask has been received

Definition at line 33 of file NetworkInterface.cpp.

virtual NetworkStack* get_stack ( ) [protected, pure virtual, inherited]

Provide access to the NetworkStack object.

Returns:: The underlying NetworkStack object

MBED_WEAK EthInterface * get_target_default_instance ( ) [static, protected]

Get the target's default Ethernet interface.

This is provided as a weak method so targets can override. The default implementation will invoke EthernetInterface with the default EMAC and default network stack, if DEVICE_EMAC is set.

Returns:: pointer to interface, if any

Definition at line 24 of file EthernetInterface.cpp.

nsapi_error_t gethostbyname	(	const char *	host,
		SocketAddress *	address,
		nsapi_version_t	version = `NSAPI_UNSPEC`
	)		`[virtual, inherited]`

Translates a hostname to an IP address with specific version.

The hostname may be either a domain name or an IP address. If the hostname is an IP address, no network transactions will be performed.

If no stack-specific DNS resolution is provided, the hostname will be resolve using a UDP socket on the stack.

Parameters:

host	Hostname to resolve
address	Destination for the host SocketAddress
version	IP version of address to resolve, NSAPI_UNSPEC indicates version is chosen by the stack (defaults to NSAPI_UNSPEC)

Returns:: 0 on success, negative error code on failure

Definition at line 58 of file NetworkInterface.cpp.

nsapi_value_or_error_t gethostbyname_async	(	const char *	host,
		hostbyname_cb_t	callback,
		nsapi_version_t	version = `NSAPI_UNSPEC`
	)		`[virtual, inherited]`

Translates a hostname to an IP address (asynchronous)

The hostname may be either a domain name or an IP address. If the hostname is an IP address, no network transactions will be performed.

If no stack-specific DNS resolution is provided, the hostname will be resolve using a UDP socket on the stack.

Call is non-blocking. Result of the DNS operation is returned by the callback. If this function returns failure, callback will not be called. In case result is success (IP address was found from DNS cache), callback will be called before function returns.

Parameters:

host	Hostname to resolve
callback	Callback that is called for result
version	IP version of address to resolve, NSAPI_UNSPEC indicates version is chosen by the stack (defaults to NSAPI_UNSPEC)

Returns:: 0 on immediate success, negative error code on immediate failure or a positive unique id that represents the hostname translation operation and can be passed to cancel

Definition at line 63 of file NetworkInterface.cpp.

nsapi_error_t gethostbyname_async_cancel ( int id ) [virtual, inherited]

Cancels asynchronous hostname translation.

When translation is cancelled, callback will not be called.

Parameters:

id	Unique id of the hostname translation operation

Returns:: 0 on success, negative error code on failure

Definition at line 68 of file NetworkInterface.cpp.

virtual MeshInterface* meshInterface ( ) [virtual, inherited]

Dynamic downcast to a MeshInterface.

Definition at line 259 of file NetworkInterface.h.

nsapi_error_t set_blocking ( bool blocking ) [virtual, inherited]

Set blocking status of connect() which by default should be blocking.

Parameters:

blocking true if connect is blocking

Returns:: 0 on success, negative error code on failure

Definition at line 87 of file NetworkInterface.cpp.

nsapi_error_t set_dhcp ( bool dhcp ) [virtual, inherited]

Enable or disable DHCP on the network.

Enables DHCP on connecting the network. Defaults to enabled unless a static IP address has been assigned. Requires that the network is disconnected.

Parameters:

dhcp	True to enable DHCP

Returns:: 0 on success, negative error code on failure

Definition at line 48 of file NetworkInterface.cpp.

nsapi_error_t set_network	(	const char *	ip_address,
		const char *	netmask,
		const char *	gateway
	)		`[virtual, inherited]`

Set a static IP address.

Configures this network interface to use a static IP address. Implicitly disables DHCP, which can be enabled in set_dhcp. Requires that the network is disconnected.

Parameters:

ip_address	Null-terminated representation of the local IP address
netmask	Null-terminated representation of the local network mask
gateway	Null-terminated representation of the local gateway

Returns:: 0 on success, negative error code on failure

Definition at line 43 of file NetworkInterface.cpp.

virtual WiFiInterface* wifiInterface ( ) [virtual, inherited]

Dynamic downcast to a WiFiInterface.

Definition at line 253 of file NetworkInterface.h.
