On the other hand, if you've already used sockets in (say) C, then it is a straightforward wrapper. So this might be more of a documentation issue (and changes from the way it works in C might steepen the learning curve). > There is not a high-level interface to it which is why I > wrote rxsock.cls. A high-level interface is good; fxftp.cls, for example, was a doddle to use when I had to convert from using the rxftp functions. The downside is when you need to set one of the obscure TCP/IP options (not necessary for FTP, in my experience) and it is not available in the higher-level model. > - I think there might be a big difference between Windows and > Linux users of rxsock, but I am not sure I can explain why. > It is just a feeling I have. > - Sockets are hard, and do not let anyone tell you > differently.

Maybe it should be task-oriented, and be higher-level than TCP/IP, even. TCP/IP and sockets are really quite low-level in the bigger (deeper, more complex) scheme of things.
