Return the IP address of the default network interface as a string

Returns

IP address as string of default network interface

Examples:

hurricane/arducam/network.c , network/tcp_echo_server/main.c , network/tcp_multiclient/main.c , and network/websocket_server/main.c .

Attempt to bring the specified network interface up.

If interface is GOS_INTERFACE_ANY first try to bringup the default interface. If that fails, try to bringup the GOS_INTERFACE_ETHERNET interface if it's not the default interface AND the platform supports the GOS_INTERFACE_ETHERNET . Else try to bringup the GOS_INTERFACE_WLAN .

Print a meaningful error message on failure.

Parameters

[in]	interface	gos_interface_t to bring up
[in]	restart	If true then restart the interface if it's already up, if false then only bring it up if it's currently down
[in]	network_event_handler	gos_network_handler_t to be invoke when the network state changes

Returns

gos_result_t , the result of the API
