GETNODEBYADDR(3) Library Functions Manual GETNODEBYADDR(3)

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); }
