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);
}
