Anything other than single bytes of data will probably get mangled unless you take care. For integer values you can use htons() and friends, and strings are really just a bunch of single bytes, so those should be OK. Be careful not to send a pointer to a string though, since the pointer will be meaningless on another machine. If you need to send a struct, you should write sendthisstruct() and readthisstruct() functions for it that do all the work of taking the structure apart on one side, and putting it back together on the other. If you need to send floats, you may have a lot of work ahead of you. You should read RFC 1014 which is about portable ways of getting data from one machine to another (thanks to Andrew Gabriel for pointing this out).
