		ACE_INET_Addr &	addr,

		const char *	specified_hostname = 0
	)			[virtual]

Set the host name for the given addr. A hostname may be forced by using specified_hostname. This is useful if the given address corresponds to more than one hostname and the desired one cannot be determined in any other way. This method is used both when constructing IOR endpoints and LPL (listen point lists).

The algorithm used is:

• If hostname_in_ior_ has been set, it is used "as is";
• else if use_dotted_decimal_addresses_ is set, the text representaion of the IP is used;
• else if specified_hostname is given, it used "as is";
• else a reverse (address to name) lookup is used to obtain the hostname or the IP if no reverse mapping exists.

Parse protocol specific options.

Currently supported: portspan -- specifies the range of ports over which the acceptor should scan looking for a free port (this is convenient for situations where you might normally use an ephemeral port but can't because you're behind a firewall and don't want to permit passage on all ephemeral ports)

int TAO_IIOP_Acceptor::parse_options_i	(	int &	argc,
		ACE_CString **	argv
	)			[protected, virtual]

Parse options splits the options list in to an argv array. This allows manipulation of the list in a manner similar to orb_init. By moving the consumed args to the tail of the list and reducing the argc count, the base parse_options_i can be called by derived parse_options_i. Method returns -1 if an ill-formed or otherwise bogus arg is encountered. The only strictly bogus arg was priority, which was a holdover from the early RT IIOP implementations. an ill-formed option is one which is missing an equal sign or something to the left of it.

Probe the system for available network interfaces, and initialize the <addrs_> array with an ACE_INET_Addr for each network interface. The port for each initialized ACE_INET_Addr will be set in the open_i() method. This method only gets invoked when no explicit hostname is provided in the specified endpoint.

The optional argument def_type is used to constrain the resulting list of interfaces to be either only IPv6 or IPv4, or both, when ACE_HAS_IPV6 is enabled and the source endpoint was an explicitly declared wildcard.
