Decnet node entry retrieval by address
#include <netdnet/dn.h>

struct nodeent *getnodebyaddr (char *addr, short len, const int family)
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
