Yes, as previously said, there are complete lwIP examples for unixes and
win32 in the lwIP contrib Git.

git://git.savannah.nongnu.org/lwip/lwip-contrib.git

Yes, definitely.

What you tried to do is not bare-metal, the "TCPIP" API is the
thread-safe API for lwIP users using an OS (NO_SYS = 0).

I am sorry, I am not sure what is meant by an OS here.

I presume if there were an OS, then the environment would "not" be bare-metal (since we would be depending on the functionalities being provided by the OS) ?
