Detailed Description

Manages a collection of sockets listening on different ports.

This class allows a TCP or UDP server to listen on a list of addresses rather than limited to a single or all addresses. This is done by opening a separate server for each defined QHostAddress, and signalling collectively for any new connections.

This can be subclassed with new 'newTcpConnection()' and 'newConnection()' methods to allow signalling for alternate socket types.

tryListeningPort

Description: Tells the server to listen for incoming connections on port port. The server will attempt to listen on all local interfaces.

Usage: baseport: port to listen on. range: range of ports to try (default 1)

Returns port used on success; otherwise returns -1.

tryBindingPort

Description: Binds this socket for incoming connections on port port. The socket will attempt to bind on all local interfaces.

Usage: baseport: port to bind to. range: range of ports to try (default 1)

Returns port used on success; otherwise returns -1.

tryListeningPort

Description: Tells the server to listen for incoming connections on port port. The server will attempt to listen on all IPv6 and IPv4 interfaces. If IPv6 isn't available, the server will listen on all IPv4 network interfaces.

Usage: server: QTcpServer object to use baseport: port to listen on. If port is 0, a port is chosen automatically. range: range of ports to try (default 1) isipv6: is set to true if IPv6 was successful (default nullptr)

Returns port used on success; otherwise returns -1.

tryBindingPort

Description: Binds this socket for incoming connections on port port. The socket will attempt to bind on all IPv6 and IPv4 interfaces. If IPv6 isn't available, the socket will be bound to all IPv4 network interfaces.

Usage: socket: QUdpSocket object to use baseport: port to bind to. range: range of ports to try (default 1) isipv6: is set to true if IPv6 was successful (default nullptr)

Returns port used on success; otherwise returns -1.
