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.

Definition at line 178 of file NetworkInterface.h.

	)		`[virtual, inherited]`

Translate 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).

Returns:: NSAPI_ERROR_OK on success, negative error code on failure.

	)		`[virtual, inherited]`

Translate a hostname to an IP address (asynchronous).

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).

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.
