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

Register a PPP interface with the IP stack.
Connects PPP layer with the IP stack and initializes all the required infrastructure. This function should be called only once for each available interface.
This is an internal function that links ppp_lwip.cpp to mbed_ipstack_lwip.cpp, once a driver starts it via the nsapi_ppp.h API.
Ultimately the nsapi_ppp.h API will be deprecated, and there will be a mbed_ipstack_add_ppp_interface() replacing nsapi_ppp_connect().

Translate a hostname to the multiple IP addresses with specific version using network interface name.

Translates a hostname to the multiple IP addresses (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.
The 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 that IP addresses are found from DNS cache, callback will be called before function returns.

Accepts a connection on a TCP socket.
The server socket must be bound and set to listen for connections. On a new connection, creates a network socket and stores it in the specified handle. The handle must be passed to following calls on the socket.
A stack may have a finite number of sockets, in this case NSAPI_ERROR_NO_SOCKET is returned if no socket is available.
This call is non-blocking. If accept would block, NSAPI_ERROR_WOULD_BLOCK is returned immediately.
