&reftitle.description; ``Socket``false```socket_create_listen` `int` `port` `int` `backlog` 128

`socket_create_listen` creates a new `Socket` instance of type `AF_INET` listening on all local interfaces on the given port waiting for new connections.

This function is meant to ease the task of creating a new socket which only listens to accept new connections.

&reftitle.parameters;

`port`

- The port on which to listen on all interfaces.

`backlog`

&reftitle.returnvalues;

`socket_create_listen` returns a new `Socket` instance on success or &false; on error. The error code can be retrieved with `socket_last_error`. This code may be passed to `socket_strerror` to get a textual explanation of the error.
