Member Typedef Documentation
typedef mbed::Callback<void (nsapi_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.
- Parameters:
-
result NSAPI_ERROR_OK on success, negative error code on failure. address On success, destination for the host SocketAddress.
Reimplemented from DNS.
Definition at line 253 of file NetworkInterface.h.
Member Function Documentation
nsapi_error_t add_dns_server | ( | const SocketAddress & | address, |
const char * | interface_name | ||
) | [virtual, inherited] |
Add a domain name server to list of servers to query.
- Parameters:
-
address Address for the dns host.
- Returns:
- NSAPI_ERROR_OK on success, negative error code on failure.
Implements DNS.
Definition at line 109 of file NetworkInterface.cpp.
void add_event_listener | ( | mbed::Callback< void(nsapi_event_t, intptr_t)> | status_cb ) | [inherited] |
Add event listener for interface.
This API allows multiple callback to be registered for a single interface. When first called, internal list of event handlers are created and registered to interface through attach() API.
Application may only use attach() or add_event_listener() interface. Mixing usage of both leads to undefined behavior.
- Parameters:
-
status_cb The callback for status changes.
Definition at line 144 of file NetworkInterface.cpp.
void attach | ( | mbed::Callback< void(nsapi_event_t, intptr_t)> | status_cb ) | [virtual, inherited] |
Register callback for status reporting.
The specified status callback function will be called on status changes on the network. The parameters on the callback are the event type and event-type dependent reason parameter. Only one callback can be registered at a time.
To unregister a callback call with status_cb parameter as a zero.
*NOTE:* Any callbacks registered with this function will be overwritten if add_event_listener() API is used.
- Parameters:
-
status_cb The callback for status changes.
Reimplemented in ESP8266Interface, CellularContext, EMACInterface, L3IPInterface, and PPPInterface.
Definition at line 114 of file NetworkInterface.cpp.
virtual CellularInterface* cellularInterface | ( | ) | [virtual, inherited] |
Return pointer to a CellularInterface.
- Returns:
- Pointer to requested interface type or NULL if this class doesn't implement the interface.
Reimplemented in CellularInterface.
Definition at line 387 of file NetworkInterface.h.
virtual nsapi_error_t connect | ( | ) | [pure virtual, inherited] |
Connect to a network.
This blocks until connection is established, but asynchronous operation can be enabled by calling NetworkInterface::set_blocking(false).
In asynchronous mode this starts the connection sequence and returns immediately. Status of the connection can then checked from NetworkInterface::get_connection_status() or from status callbacks.
NetworkInterface internally handles reconnections until disconnect() is called.
- Returns:
- NSAPI_ERROR_OK if connection established in blocking mode.
- NSAPI_ERROR_OK if asynchronous operation started.
- NSAPI_ERROR_BUSY if asynchronous operation cannot be started. Implementation guarantees event generation, which can be used as an trigger to reissue the rejected request.
- NSAPI_ERROR_IS_CONNECTED if already connected.
- negative error code on failure.
Implemented in ESP8266Interface, CellularContext, CellularInterface, EMACInterface, L3IPInterface, PPPInterface, and WiFiInterface.
virtual nsapi_error_t disconnect | ( | ) | [pure virtual, inherited] |
Disconnect from the network.
This blocks until interface is disconnected, unless interface is set to asynchronous (non-blocking) mode by calling NetworkInterface::set_blocking(false).
- Returns:
- NSAPI_ERROR_OK on successfully disconnected in blocking mode.
- NSAPI_ERROR_OK if asynchronous operation started.
- NSAPI_ERROR_BUSY if asynchronous operation cannot be started. Implementation guarantees event generation, which can be used as an trigger to reissue the rejected request.
- NSAPI_ERROR_NO_CONNECTION if already disconnected.
- negative error code on failure.
Implemented in ESP8266Interface, CellularContext, CellularInterface, EMACInterface, L3IPInterface, PPPInterface, and WiFiInterface.

If no stack-specific DNS resolution is provided, the hostname will be resolve using a UDP socket on the stack.

hostbyname_cb_t | callback, | ||
nsapi_version_t | version = NSAPI_UNSPEC , |
||
const char * | interface_name = NULL |
||
) | [virtual, inherited] |
Translate a hostname to an IP address (asynchronous) using network interface name.
The hostname may be either a domain name or a dotted 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.
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 result is success (IP address was found from DNS cache), callback will be called before function returns.
- Parameters:
-
host Hostname to resolve. callback Callback that is called for 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
- Returns:
- 0 on immediate success, negative error code on immediate failure or a positive unique id that represents the hostname translation operation and can be passed to cancel.
