typedef basic_resolver_results< InternetProtocol > results_type;
Types

Name

Description

const_iterator

The type of an iterator into the range.

const_reference

The type of a const reference to a value in the range.

difference_type

Type used to represent the distance between two iterators in the range.

endpoint_type

The endpoint type associated with the results.

iterator

The type of an iterator into the range.

iterator_category

The iterator category.

pointer

The type of the result of applying operator->() to the iterator.

protocol_type

The protocol type associated with the results.

reference

The type of a non-const reference to a value in the range.

size_type

Type used to represent a count of the elements in the range.

value_type

The type of a value in the results range.

Description

operator!=

Test two iterators for inequality.

operator==

Test two iterators for equality.

The ip::basic_resolver_results class template is used to define a range over the results returned by a resolver.

The iterator's value_type, obtained when a results iterator is dereferenced, is:

const basic_resolver_entry<InternetProtocol>
Remarks

For backward compatibility, ip::basic_resolver_results is derived from ip::basic_resolver_iterator. This derivation is deprecated.

Thread Safety

Distinct objects: Safe.

Shared objects: Unsafe.
