Call when you are finished writing the contents of a single packet.
Calling EndPacket is not strictly necessary, but it is good style, and it allows .NET/Link to immediately generate a MathLinkException if you are not actually finished with writing the data you promised to send.
| Exception Type | Condition | 
|---|---|
| MathLinkException | On any MathLink error. |
