Member Typedef Documentation

typedef mbed::Callback<void (nsapi_error_t result, SocketAddress *address) hostbyname_cb_t) [inherited]

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.

Parameters:

status	0 on success, negative error code on failure
address	On success, destination for the host SocketAddress

Definition at line 180 of file NetworkInterface.h.

void attach ( mbed::Callback< void(nsapi_event_t, intptr_t)> status_cb ) [virtual, inherited]

Get the local MAC address.

Provided MAC address is intended for info or debug purposes and may not be provided if the underlying network interface does not provide a MAC address

Returns:: Null-terminated representation of the local MAC address or null if no MAC address is available

Definition at line 23 of file NetworkInterface.cpp.

virtual const char* get_netmask ( ) [pure virtual]

Get the local network mask.

Returns:: Null-terminated representation of the local network mask or null if no network mask has been received

Implemented in EasyCellularConnection.

Definition at line 67 of file OnboardCellularInterface.cpp.

nsapi_error_t gethostbyname	(	const char *	host,
		SocketAddress *	address,
		nsapi_version_t	version = `NSAPI_UNSPEC`
	)		`[virtual, inherited]`

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	Destination for the host SocketAddress
version	IP version of address to resolve, NSAPI_UNSPEC indicates version is chosen by the stack (defaults to NSAPI_UNSPEC)

Returns:: 0 on success, negative error code on failure

Definition at line 58 of file NetworkInterface.cpp.

nsapi_value_or_error_t gethostbyname_async	(	const char *	host,
		hostbyname_cb_t	callback,
		nsapi_version_t	version = `NSAPI_UNSPEC`
	)		`[virtual, inherited]`

Translates a hostname to an IP address (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.

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)

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

Definition at line 63 of file NetworkInterface.cpp.

nsapi_error_t gethostbyname_async_cancel ( int id ) [virtual, inherited]

Cancels asynchronous hostname translation.

When translation is cancelled, callback will not be called.

Definition at line 68 of file NetworkInterface.cpp.

virtual bool is_connected ( ) [pure virtual]

Check if the connection is currently established or not.
