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);
}
