The AddUDP method creates a new FPCProtocolConnection object for a UDP connection and returns a reference to it.

HRESULT AddUDP(
  FpcUDPConnectionDirectionType Direction,
  long PortLo,
  long PortHi,
  IFPCProtocolConnection** ppNewProtocolConnection
);

Parameters

Direction

[in] Required. Value from the FpcUDPConnectionDirectionType enumerated type that specifies the direction for the new connection.

PortLo

[in] Lower bound of the port range used in the connection.

PortHi

[in] Upper bound of the port range used in the connection.

ppNewProtocolConnection

[out] Address of an interface pointer that on return points to the new IFPCProtocolConnection interface created.

Return Values

This method can return one of the following:

• S_OK, indicating that the operation succeeded.
• An error code, indicating that the operation failed. In this case, the [out] parameter returned is a null object.
