NAME
       getnodebyaddr - DECnet node entry retrieval by address

SYNOPSIS
       #include <netdnet/dn.h>
       #include <netdnet/dnetdb.h>

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

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

EXAMPLE
       #include <netdnet/dn.h>
       #include <netdnet/dnetdb.h>
       #include <sys/socket.h>

       main(void)
       {
	   struct dn_naddr	binaddr;
	   struct nodeent	*dp;

	   binaddr->a_len = 2;
	   binaddr->a_addr[0] = 0x02;
	   binaddr->a_addr[1] = 0x04;

	   if ( (dp=getnodebyaddr(binaddr->a_addr,binaddr->len, PF_DECnet)) == NULL)
	       printf("Error, cannot find node entry");
	   else
	       printf("Node name is %s",dp->n_name);
       }
