Member Typedef Documentation

◆ hostbyname_cb_t

typedef mbed::Callback<void (nsapi_value_or_error_t result, SocketAddress *address)> hostbyname_cb_t

inherited

Hostname translation callback (for use with gethostbyname_async()).

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

Note: 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.

result : Negative error code on failure, or value that represents the number of DNS records
address : On success, destination for the host SocketAddress.

Definition at line 285 of file NetworkInterface.h.

Definition at line 145 of file MeshInterfaceNanostack.h.

◆ get_default_instance() [1/2]

static NetworkInterface * get_default_instance ( )

staticinherited

Return the default network interface.

Returns the default network interface, as determined by JSON option target.network-default-interface-type or other overrides.

The type of the interface returned can be tested by calling ethInterface(), wifiInterface(), meshInterface(), cellularInterface(), emacInterface() and checking for NULL pointers.

The default behavior is to return the default interface for the interface type specified by target.network-default-interface-type. Targets should set this in their targets.json to guide default selection, and applications may override.

The interface returned should be already configured for use such that its connect() method works with no parameters. For connection types needing configuration, settings should normally be obtained from JSON - the settings for the core types are under the "nsapi" JSON config tree.

The list of possible settings for default interface type is open-ended, as is the number of possible providers. Core providers are:

ETHERNET: EthernetInterface, using default EMAC and OnboardNetworkStack
MESH: ThreadInterface or LoWPANNDInterface, using default NanostackRfPhy
CELLULAR: OnboardModemInterface
WIFI: None - always provided by a specific class

Specific drivers may be activated by other settings of the default-network-interface-type configuration. This will depend on the target and the driver. For example a board may have its default setting as "AUTO" which causes it to autodetect an Ethernet cable. This should be described in the target's documentation.

An application can override all target settings by implementing NetworkInterface::get_default_instance() themselves - the default definition is weak, and calls get_target_default_instance().

◆ get_default_instance() [2/2]

static MeshInterface * get_default_instance ( )

Get the default Mesh interface.

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