I really thought this would be easier to find...

I need a portable c++ sockets wrapper. I'm planning to use it for a windows server application and a client that will be running on a embedded device running ulinux (or something similar). I would use Boost but I need it to be lightweight and easy to add to the embedded device project.

Also I would like it to be a "higher level" wrapper... so it starts a background thread to read data and informs be over a callback...

Any ideas?

Just learn to use the socket API directly. You can then easily wrap it yourself. It's not that hard, and you can get started with Beej's excellent guide. As Beej says:

The sockets API, though started by the Berkeley folk, has been ported to many many platforms, including Unix, Linux, and even Windows.

In his guide he details the very small addition you need to do to get the same API in Windows and *nix systems.

Once you've learned, wrap it yourself if you're so inclined. Then you can control exactly how "lightweight" you want it.

网友答案:

I'd suggest Boost.Asio. Despite it's name, you are not forced to use asynchronous I/O. You could use synchronous I/O and threads, as your question implies.

Boost.Asio is a cross-platform C++ library for network and low-level I/O programming that provides developers with a consistent asynchronous model using a modern C++ approach.

网友答案:

If you really don't like Boost asio then you might like the sockets support in dlib. It is simpler in the sense that it uses traditional blocking IO and threads rather than asio's asynchronous proactor pattern. For example, it makes it easy to make a threaded TCP server that reads and writes from the iostreams. See this example for instance. Or you can just make a simple iosockstream if not acting as a server.

I know this is old, but there is a very nice and simple implementation in below location which I'm using for personal use. Had implemented my own wrapper a while back but lost the code and found this one online which is much better than mine:

Perhaps you can have a look at http://www.pt-framework.org/

网友答案:

Take a look at ENet http://enet.bespin.org/ it is very lightweight and portable and works on top of UDP, with optional support for reliable packets. It is easy to use, the API is low-level and with little performance overhead. You have a high degree of control over the memory management, which could be good if networking is a bottleneck for you and the malloc/new implementation you use performs badly under multithreading.

It would not be that hard to implement your high level thread “optimally”, since there is optional support for blocking receive and the library is a “library” and not a framework therefore you are the decision maker instead of the library.

网友答案:

Old question, but for C++, BSD style synchronous sockets this is about as minimal baggage wrapper as you can find http://code.google.com/p/ting/source/browse/trunk/src/ting/net/

It does come with exceptions. You could make a bit more lightweight one as a header-only template library, and maybe make exceptions optional, but that would change the API a bit

POCO network classes are quite similar, but do require more dependencies from other parts of the Poco lib

Used it loved it. Stable and powerful
