I'm trying to compile your example, but I can't get it to compile, it looks like I need to declare more functions(like putcconn), but where? in a different file or do I need another library besides the one you stated before??
Hope you or someone can help me?
Thanks a lot.

Sorry, this is code taken from a bigger library, I forgot to throw out these two lines.
See my original post for an updated version of the code.

Edit: You need to fix your build environment first, you should never include things in /usr/include/, these are files for your build machine, rather than the esp.

Thanks for replying, I will take a look at your code.
