g_socket_listener_add_any_inet_port (
  GSocketListener* listener,
  GObject* source_object,
  GError** error
)

Description

Listens for TCP connections on any available port number for both IPv6 and IPv4 (if each is available).

This is useful if you need to have a socket for incoming connections but don’t care about the specific port number.

source_object will be passed out in the various calls to accept to identify this particular source, which is useful if you’re listening on multiple addresses and do different things depending on what address is connected to.

Available since: 2.24

Parameters

source_object

Type: GObject

Optional GObject identifying this source.

The argument can be NULL.

The data is owned by the caller of the function.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will left initialized to NULL by the method if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: guint16

The port number, or 0 in case of failure.
