DNET_ADDR(3)						     Library Functions Manual						      DNET_ADDR(3)

NAME
       dnet_addr - DECnet nodename to address translation

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

       struct dn_naddr *dnet_addr (char *nodename)

DESCRIPTION
       dnet_addr search the decnet hosts file for nodename and returns the DECnet address in the dn_naddr 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 sockaddr_dn	     sockaddr;
	   int			sockfd;

	   if ( (binaddr=dnet_addr("mv3100")) == NULL)
	   {
	       printf("No entry in /etc/decnet.conf for mv3100
");
	       exit(0);
	    }
	    if ((sockfd=socket(AF_DECnet,SOCK_SEQPACKET,DNPROTO_NSP)) == -1)
	    {
		 perror("socket");
		 exit(-1);
	    }

	    sockaddr.sdn_family      = AF_DECnet;
	    sockaddr.sdn_flags	     = 0x00;
	    sockaddr.sdn_objnum = 0x19; 	    /* MIRROR */
	    sockaddr.sdn_objnamel    = 0x00;
	    memcpy(sockaddr.sdn_add.a_addr, binaddr->a_addr,binaddr->a_len);

	    if (connect(sockfd, (struct sockaddr *)&sockaddr,
		 sizeof(sockaddr)) < 0)
	    {
		 perror("connect");
		 exit(-1);
	    }
	    close(sockfd);
       }
