# PartyLocalUdpSocketBindAddressOptions

> Additional options to control how the Party library binds to the UDP socket specified by the.

Additional options to control how the Party library binds to the UDP socket specified by the [PartyLocalUdpSocketBindAddressConfiguration](/services/playfab/multiplayer/networking/reference/structs/partylocaludpsocketbindaddressconfiguration) structure.

## Syntax

```cpp theme={null}
enum class PartyLocalUdpSocketBindAddressOptions    
{  
    None = 0x0,  
    ExcludeGameCorePreferredUdpMultiplayerPort = 0x1,  
}  
```

| None                                       | No flags are specified.<br /><br /> This value is the default if a [PartyLocalUdpSocketBindAddressConfiguration](/services/playfab/multiplayer/networking/reference/structs/partylocaludpsocketbindaddressconfiguration) structure has not been explicitly set.                                                                                                                                                                                                                                                                                                                       |
| ExcludeGameCorePreferredUdpMultiplayerPort | Don't default to using the Microsoft Game Core preferred UDP multiplayer port when the port is unspecified.<br /><br /> In the Microsoft Game Core version of the Party library, when the *port* field of the [PartyLocalUdpSocketBindAddressConfiguration](/services/playfab/multiplayer/networking/reference/structs/partylocaludpsocketbindaddressconfiguration) structure is 0, this flag informs the Party library to not use the Game Core preferred UDP multiplayer port. In other versions of the Party library or if the *port* port is non-zero, this flag must not be set. |
