NAME
getnodebyaddr - DECnet node entry retrieval by address
SYNOPSIS
#include <netdnet/dn.h>
#include <netdnet/dnetdb.h>
struct nodeent *getnodebyaddr (char *addr, short len, const int family)
DESCRIPTION
getnodebyaddr searches the decnet hosts file for the DECnet node with
address equal to addr of len bytes, belonging to protocol family family
(PF_DECnet) and returns node information into the nodeent 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 nodeent *dp;
binaddr->a_len = 2;
binaddr->a_addr[0] = 0x02;
binaddr->a_addr[1] = 0x04;
if ( (dp=getnodebyaddr(binaddr->a_addr,binaddr->len, PF_DECnet)) == NULL)
printf("Error, cannot find node entry");
else
printf("Node name is %s",dp->n_name);
}
