NAME

dnet_getnode, dnet_nextnode, dnet_endnode - Get nodes from DECnet database

SYNOPSIS

#include <netdnet/dn.h>
#include <netdnet/dnetdb.h>

void *dnet_getnode (void)
char *dnet_nextnode (void *)
void dnet_endnode (void *)

DESCRIPTION

dnet_getnode() Starts the search of the DECnet nodes database (/etc/decnet.conf). It returns an opaque pointer which is passed to the other two functions.
dnet_nextnode() returns the next node name in the list. The pointer is private to the library and will be overwritten at the next dnet_nextnode call. dnet_endnode() ends the search. It must be called when you have finished with this group of functions or a memory leak will result.

EXAMPLE

 
 #include <netdnet/dn.h>
 #include <netdnet/dnetdb.h>
 #include <sys/socket.h>
 
 main(void)
 {
   void *nodelist;
   char *nodename;
 
   nodelist = dnet_getnode();
   nodename = dnet_nextnode(nodelist);
   while(nodename)
   {
       printf("Found node %s\n", nodename);
       nodename = dnet_nextnode(nodelist);
   }
   dnet_endnode(nodelist);
 
 }
