getnodebyaddr - DECnet node entry retrieval by address

getnodebyaddr searches the decnet hosts file for the DECnet node with address equal to addr of len bytes,
       belonging to protocol family family (PF_DECnet) and returns node information into the nodeent structure.
       If no entry is found, returns NULL
