Definition at line 50 of file FEATURE_LWIP/lwip-interface/EthernetInterface.cpp.

static int disconnect (  ) [static, virtual]

Disconnect Bring the interface down.

Returns:
0 on success, a negative number on failure

Implements NetworkInterface.

const char * get_gateway (  ) [virtual]

Get the local gateways.

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

Reimplemented from NetworkInterface.

Definition at line 78 of file FEATURE_LWIP/lwip-interface/EthernetInterface.cpp.

const char * get_ip_address (  ) [virtual]

Get the local IP address.

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

Reimplemented from NetworkInterface.

Definition at line 60 of file FEATURE_LWIP/lwip-interface/EthernetInterface.cpp.

const char * get_mac_address (  ) [virtual]

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

Reimplemented from NetworkInterface.

Definition at line 55 of file FEATURE_LWIP/lwip-interface/EthernetInterface.cpp.

const char * get_netmask (  ) [virtual]

Get the local network mask.

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

Reimplemented from NetworkInterface.

Definition at line 69 of file FEATURE_LWIP/lwip-interface/EthernetInterface.cpp.

NetworkStack * get_stack ( void   ) [protected, virtual]

Provide access to the underlying stack.

Returns:
The underlying network stack

Implements NetworkInterface.

Definition at line 87 of file FEATURE_LWIP/lwip-interface/EthernetInterface.cpp.

char * getGateway (  ) [static]

Get the Gateway address of your Ethernet interface.

Returns:
a pointer to a string containing the Gateway address

Definition at line 148 of file unsupported/net/eth/EthernetInterface/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:
addressDestination for the host SocketAddress
hostHostname to resolve
versionIP 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

char * getNetworkMask (  ) [static]

Get the Network mask of your Ethernet interface.

Returns:
a pointer to a string containing the Network mask

Definition at line 152 of file unsupported/net/eth/EthernetInterface/EthernetInterface.cpp.

int init (  ) [static]

Initialize the interface and configure it with the following static configuration (no connection at this point).

Parameters:
ipthe IP address to use
maskthe IP address mask
gatewaythe gateway to use
Returns:
0 on success, a negative number on failure

Definition at line 92 of file unsupported/net/eth/EthernetInterface/EthernetInterface.cpp.

nsapi_error_t set_dhcp ( bool  dhcp ) [virtual]

Enable or disable DHCP on the network.

Requires that the network is disconnected

Parameters:
dhcpFalse to disable dhcp (defaults to enabled)
Returns:
0 on success, negative error code on failure

Reimplemented from NetworkInterface.

Definition at line 36 of file FEATURE_LWIP/lwip-interface/EthernetInterface.cpp.

nsapi_error_t set_network ( const char *  ip_address,
