.SH NAME
dnet_addr \- DECnet nodename to address translation
.SH SYNOPSIS
.B #include <netdnet/dn.h>
.br
.B #include <netdnet/dnetdb.h>
.br
.sp
.B struct dn_naddr *dnet_addr (char *nodename)
.sp
.SH DESCRIPTION
.B dnet_addr
search the decnet hosts file for
.B nodename
and returns the DECnet address in the
.B dn_naddr
structure
.br
If no entry is found, returns
.B NULL
.SH EXAMPLE
.nf
#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)
{
