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); }
