bind method

Future<RawServerSocket> bind (

1. dynamic address,
2. int port,
3. {int backlog = 0,
4. bool v6Only = false,
5. bool shared = false}

)

Listens on a given address and port.

When the returned future completes the server socket is bound to the given address and port and has started listening on it.

The address can either be a String or an InternetAddress. If address is a String, bind will perform a InternetAddress.lookup and use the first value in the list. To listen on the loopback adapter, which will allow only incoming connections from the local host, use the value InternetAddress.loopbackIPv4 or InternetAddress.loopbackIPv6. To allow for incoming connection from the network use either one of the values InternetAddress.anyIPv4 or InternetAddress.anyIPv6 to bind to all interfaces or the IP address of a specific interface.

If an IP version 6 (IPv6) address is used, both IP version 6 (IPv6) and version 4 (IPv4) connections will be accepted. To restrict this to version 6 (IPv6) only, use v6Only to set version 6 only.

If port has the value 0 an ephemeral port will be chosen by the system. The actual port used can be retrieved using the port getter.

The optional argument backlog can be used to specify the listen backlog for the underlying OS listen setup. If backlog has the value of 0 (the default) a reasonable value will be chosen by the system.

The optional argument shared specifies whether additional RawServerSocket objects can bind to the same combination of address, port and v6Only. If shared is true and more RawServerSockets from this isolate or other isolates are bound to the port, then the incoming connections will be distributed among all the bound RawServerSockets. Connections can be distributed over multiple isolates this way.

Implementation

external static Future<RawServerSocket> bind(address, int port,
    {int backlog = 0, bool v6Only = false, bool shared = false});
