Member Function Documentation

int add_dns_server ( const SocketAddress &  address ) [virtual]

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

Parameters:
addrDestination for the host address
Returns:
0 on success, negative error code on failure

Definition at line 68 of file NetworkInterface.cpp.

virtual int connect (  ) [pure virtual]

Start the interface.

Returns:
0 on success, negative error code on failure

Implemented in EthernetInterface, CellularInterface, and WiFiInterface.

virtual int disconnect (  ) [pure virtual]

Stop the interface.

Returns:
0 on success, negative error code on failure

Implemented in EthernetInterface, CellularInterface, WiFiInterface, and EthernetInterface.

const char * get_gateway (  ) [virtual]

Get the local gateway.

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

Reimplemented in EthernetInterface.

Definition at line 38 of file NetworkInterface.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 in EthernetInterface.

Definition at line 28 of file NetworkInterface.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 in EthernetInterface.

Definition at line 23 of file NetworkInterface.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 in EthernetInterface.

Definition at line 33 of file NetworkInterface.cpp.

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

Provide access to the NetworkStack object.

Returns:
The underlying NetworkStack object

Implemented in EthernetInterface.

int gethostbyname ( const char *  host,
SocketAddress *  address,
nsapi_version_t  version 
) [virtual]

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
Returns:
0 on success, negative error code on failure

Definition at line 63 of file NetworkInterface.cpp.

int gethostbyname ( const char *  host,
SocketAddress *  address 
) [virtual]

Translates a hostname to an IP address.

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
Returns:
0 on success, negative error code on failure

Definition at line 58 of file NetworkInterface.cpp.

int set_dhcp ( bool  dhcp ) [virtual]

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:
dhcpTrue to enable DHCP
Returns:
0 on success, negative error code on failure

Reimplemented in EthernetInterface.

Definition at line 48 of file NetworkInterface.cpp.

int set_network ( const char *  ip_address,
const char *  netmask,
const char *  gateway 
) [virtual]

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:
addressNull-terminated representation of the local IP address
netmaskNull-terminated representation of the local network mask
gatewayNull-terminated representation of the local gateway
Returns:
0 on success, negative error code on failure

Reimplemented in EthernetInterface.

Definition at line 43 of file NetworkInterface.cpp.
