If you don't even know what it is, then how do you know you need it? 
stat() is normally a function provided by a (POSIX-compatible) OS. Not a 
networking function.

stat() has no relation to lwIP at all. I suggest you google for "POSIX stat"

A variant of stat() called fstat() allows you to get information from a 
file descriptor, and you could argue that that could be related to lwIP 
since a BSD-style sockets interface normally works on file descriptors. 
But lwIP's BSD compatibility API is only, well, a compatibility API. It 
does not work on real file descriptors. That would require a huge amount 
of integration with the OS which does not exist for any OS.

Even on OSes with integrated network stacks, fstat() is not useful on 
sockets. Just about all it can tell you is that the file descriptor is not 
really a file.
