How to use the TCPStream class

[Anders Backman]

Hi all.

I have recently started to look into the Networking functionality of CommonC++.
I have been using the Threads for a while (Works great by the way).

Im trying to use the TCPStream and build a client server.

Im having problems using it. The example (tcp.cpp) is not complete? It seems to me that there is a client missing?

I have several problems:

1. If I send a string with:

tcp<<"Hello world" << endl;

It will be read on the other side as:

tcp >> buffer; // Contains "Hello"
tcp >> buffer; // Contains "world"

2. How can you check that both sides are active?
I have tried the setKeepAlive(true) and checking with isConnected() which returns true even if the other side is long gone.

3. The isPending(SOCKET_PENDING_INPUT,2000) seems to indicate that data is available even if the other side is long gone.

4. What does endl do for the functionality?
Will it insert a new-line in the string or will
it call sync() to send data?

What Im looking for really, is an example of sending/reading data.

Is there anyone out there that could help me out?

Kind regards
Anders.

There actually is a "client" example now found in urlfetch.cpp that uses the URLStream class.

1.

You may need to use the getline() method for line oriented parsing.

2.

The eof() indicator should show when a remote connection has gone.

3.

You can also do a SOCKET_PENDING_ERROR to test the exception status.

4.

endl performs a flush and adds '\n'.
