g_socket_new (
  GSocketFamily family,
  GSocketType type,
  GSocketProtocol protocol,
  GError** error


Creates a new GSocket with the defined family, type and protocol. If protocol is 0 (G_SOCKET_PROTOCOL_DEFAULT) the default protocol type for the family and type is used.

The protocol is a family and type specific int that specifies what kind of protocol to use. GSocketProtocol lists several common ones. Many families only support one protocol, and use 0 for this, others support several and using 0 means to use the default protocol for the family and type.

The protocol id is passed directly to the operating system, so you can use protocols not listed in GSocketProtocol if you know the protocol number used for it.

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
