inet_ntoa
          
                 
   Converts an (Ipv4) Internet network address to an ASCII string representing the address in ".'' (dot) notation as in "192.168.1.100''.  This string resides in memory allocated and is only guaranteed to be valid until the next Windows Sockets function call within the same thread. Therefore, the data should be copied to a local variable before making subsequent Windows Socket calls.
