/**
* This constructor is typically used to perform name resolution for local
* service binding with a specific protocol version.
*
* @param protocol A protocol object, normally representing either the IPv4 or
* IPv6 version of an internet protocol.
*
* @param service_name A string identifying the requested service. This may
* be a descriptive name or a numeric string corresponding to a port number.
*
* @param resolve_flags A set of flags that determine how name resolution
* should be performed. The default flags are suitable for local service
* binding.
*
* @note On POSIX systems, service names are typically defined in the file
* <tt>/etc/services</tt>. On Windows, service names may be found in the file
* <tt>c:\\windows\\system32\\drivers\\etc\\services</tt>. Operating systems
* may use additional locations when resolving service names.
