ip::udp::resolver

The UDP resolver type.

typedef basic_resolver< udp > resolver;

Name	Description
endpoint_type	The endpoint type.
executor_type	The type of the executor associated with the object.
flags	A bitmask type (C++ Std [lib.bitmask.types]).
iterator	(Deprecated.) The iterator type.
protocol_type	The protocol type.
query	(Deprecated.) The query type.
results_type	The results type.

Name	Description
async_resolve	(Deprecated: Use overload with separate host and service parameters.) Asynchronously perform forward resolution of a query to a list of entries. — Asynchronously perform forward resolution of a query to a list of entries. — Asynchronously perform reverse resolution of an endpoint to a list of entries.
basic_resolver	Constructor. — Move-construct a basic_resolver from another.
cancel	Cancel any asynchronous operations that are waiting on the resolver.
get_executor	Get the executor associated with the object.
get_io_context	(Deprecated: Use get_executor().) Get the io_context associated with the object.
get_io_service	(Deprecated: Use get_executor().) Get the io_context associated with the object.
operator=	Move-assign a basic_resolver from another.
resolve	(Deprecated: Use overload with separate host and service parameters.) Perform forward resolution of a query to a list of entries. — Perform forward resolution of a query to a list of entries. — Perform reverse resolution of an endpoint to a list of entries.
~basic_resolver	Destroys the resolver.

Name	Description
address_configured	Only return IPv4 addresses if a non-loopback IPv4 address is configured for the system. Only return IPv6 addresses if a non-loopback IPv6 address is configured for the system.
all_matching	If used with v4_mapped, return all matching IPv6 and IPv4 addresses.
canonical_name	Determine the canonical name of the host specified in the query.
numeric_host	Host name should be treated as a numeric string defining an IPv4 or IPv6 address and no name resolution should be attempted.
numeric_service	Service name should be treated as a numeric string defining a port number and no name resolution should be attempted.
passive	Indicate that returned endpoint is intended for use as a locally bound socket endpoint.
v4_mapped	If the query protocol family is specified as IPv6, return IPv4-mapped IPv6 addresses on finding no IPv6 addresses.

The ip::basic_resolver class template provides the ability to resolve a query to a list of endpoints.

Distinct objects: Safe.
