me again 
now i'm using MS SOCKET. in function ezUdp::relate() i create it and bind it. function ezUdp::establish calls relate and then sendto(), which fails.
run the program and write local IP and a port in the upper left corner and enter another IP and port in the upper right corner. write something in the left field and "send". you can see it (sendto()) complains it is not a valid socket.
if you write an IP other then your own, which should cause bind() to fail, you can see it still complains at sendto(), instead of bind(), i.e., establish() does not throw the exception relate() throws. if you explicitly throw a std::string, it just works same.
if i move the operations from relate() to establish(), it runs well.
note that ezcommon directory is to hold header files only, and need not be compiled.
