◆ gethostbyname()

virtual nsapi_error_t gethostbyname	(	const char *	host,
		SocketAddress *	address,
		nsapi_version_t	version = `NSAPI_UNSPEC`,
		const char *	interface_name = `NULL`
	)

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

host	Hostname to resolve
address	Pointer to a SocketAddress to store the result.
version	IP version of address to resolve, NSAPI_UNSPEC indicates version is chosen by the stack (defaults to NSAPI_UNSPEC)
interface_name	Network interface_name

Return values

NSAPI_ERROR_OK	on success
NSAPI_ERROR_PARAMETER	if invalid (null) name is provided
NSAPI_ERROR_DNS_FAILURE	if DNS resolution fails
int	other negative errors, see nsapi_dns_query

Reimplemented from NetworkStack.

◆ socket_listen()

backlog	Number of pending connections that can be queued simultaneously

Returns: NSAPI_ERROR_OK on success, negative error code on failure

Reimplemented from AT_CellularStack.

◆ socket_accept()

virtual nsapi_error_t socket_accept	(	nsapi_socket_t	server,
		nsapi_socket_t *	handle,
		SocketAddress *	address = `0`
	)

protectedvirtual

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.

Parameters

server	Socket handle to server to accept from
handle	Destination for a handle to the newly created socket
address	Destination for the remote address or NULL

Returns: NSAPI_ERROR_OK on success, negative error code on failure

Reimplemented from AT_CellularStack.

◆ socket_open()

virtual nsapi_error_t socket_open	(	nsapi_socket_t *	handle,
		nsapi_protocol_t	proto
	)

protectedvirtualinherited

Note: Socket_open does not actually open socket on all drivers, but that's deferred until calling sendto.

The reason is that IP stack implementations are very much modem specific and it's quite common that when a socket is created (via AT commands) it must also be given remote IP address, and that is usually known only when calling sendto.
