示例1: recvPacket
/**
Reads data and returns a pointer to a new PacketBuffer object. You are responsible for
deleting the returned packet when you are finished with it.
You are gerented to receive a full PacketBuffer object.
When data is read in, some verification is done to ensure that the packet header is
valid. There is no way to validate the buffer portion of the packet. A test is done
on the header to see if the cookie (just a constant value passed all the time) and
to see the the command looks like it might be valid. There is no way to tell other then
if the command is zero (PacketBuffer::pcInvalid). Note that a common problem with getting
PacketBuffer::pcInvalid as a command is not setting the command in a packet before sending
it.
If a packet is sent with a size greater then 3000 bytes, the read operation will
reset the internal buffer, and throw an exception. This is done to prevent bogus packets
overflowing the buffer.
\throw SocketInstanceException If there is a read error, or a connection was closed.
\throw BufferedSocketException If a bad packet was read.
