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>

exit(0); - }
if ((sockfd=socket(AF_DECnet,SOCK_SEQPACKET,DNPROTO_NSP)) == -1)
