man dnet_addr (Fonctions bibliothèques) - DECnet nodename to address translation

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\n");
	   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);
}
