b2bits::net::UdpEndpoint Struct Reference

UDP-specific endpoint with local binding address. More...

Detailed Description

UDP-specific endpoint with local binding address.

Extends Endpoint with an additional local IP address field for UDP sockets. This allows specifying which local network interface to bind to when receiving multicast traffic or binding to a specific interface.

The local_ip_ field is used for:

• Multicast group subscription (join multicast on specific interface)
• Binding UDP sockets to specific network interfaces
• Handling multi-homed systems (multiple network interfaces)

Note

Inherits ip_ (remote/multicast address) and port_ from Endpoint

Default local_ip_ is "0.0.0.0" (INADDR_ANY - all interfaces)

Example:

// Multicast endpoint
UdpEndpoint multicast;
multicast.ip_ = "239.1.1.1";       // Multicast group
multicast.port_ = 12345;            // Multicast port
multicast.local_ip_ = "192.168.1.10";  // Bind to specific interface
 
// Default (bind to all interfaces)
UdpEndpoint any_interface;
any_interface.ip_ = "239.2.2.2";
any_interface.port_ = 54321;
// local_ip_ = "0.0.0.0" (default)
