Unity.Networking.Transport.NetworkPacketReceiver

The NetworkPacketReceiver is an interface for handling received packets, needed by the INetworkInterface It either can be used in two main scenarios:

1. Your API requires a pointer to memory that you own. Then you should use AllocateMemory(ref Int32), write to the memory and then AppendPacket(IntPtr, ref NetworkInterfaceEndPoint, Int32, NetworkPacketReceiver.AppendPacketMode) with NoCopyNeeded. You don't need to deallocate the memory
2. Your API gives you a pointer that you don't own. In this case you should use AppendPacket(IntPtr, ref NetworkInterfaceEndPoint, Int32, NetworkPacketReceiver.AppendPacketMode) with None (default)

Syntax

public struct NetworkPacketReceiver

LastUpdateTime

Declaration

public readonly long LastUpdateTime { get; }

Property Value

Type	Description
System.Int64

ReceiveErrorCode

Declaration

public int ReceiveErrorCode { set; }

Property Value

Type	Description
System.Int32

AllocateMemory(ref Int32)

Calls NetworkDriver's AllocateMemory(ref Int32)

Declaration

public IntPtr AllocateMemory(ref int dataLen)

Parameters

Type	Name	Description
System.Int32	dataLen	Size of memory to allocate in bytes. Must be > 0

Returns

Type	Description
System.IntPtr	Pointer to allocated memory or IntPtr.Zero if there is no space left (this function doesn't set ReceiveErrorCode! caller should decide if this is Out of memory or something else)

AppendPacket(IntPtr, ref NetworkInterfaceEndPoint, Int32, NetworkPacketReceiver.AppendPacketMode)

When data is received this function should be called to pass it inside NetworkDriver

Declaration

public bool AppendPacket(IntPtr data, ref NetworkInterfaceEndPoint address, int dataLen, NetworkPacketReceiver.AppendPacketMode mode = NetworkPacketReceiver.AppendPacketMode.None)

Parameters

Type	Name	Description
System.IntPtr	data	Pointer to the data. If it is pointer to data that was received with AllocateMemory(ref Int32) make sure mode is NoCopyNeeded>
NetworkInterfaceEndPoint	address	Address where data was received from
System.Int32	dataLen	Length of in bytes
NetworkPacketReceiver.AppendPacketMode	mode	Extra flags, like NoCopyNeeded that means - no copy is needed, data is already in NetworkDriver's data stream

Returns

Type	Description
System.Boolean	True if no errors

IsAddressUsed(NetworkInterfaceEndPoint)

Check if an address is currently associated with a valid connection. This is mostly useful to keep interface internal lists of connections in sync with the correct state.

Declaration

public bool IsAddressUsed(NetworkInterfaceEndPoint address)

Parameters

Type	Name	Description
NetworkInterfaceEndPoint	address

Returns

Type	Description
System.Boolean
