.SH NAME
dnet_getnode, dnet_nextnode, dnet_endnode \- Get nodes from DECnet database
.SH SYNOPSIS
.B #include <netdnet/dn.h>
.br
.B #include <netdnet/dnetdb.h>
.br

.B void *dnet_getnode (void)

.B  void dnet_endnode (void *)
.sp
.SH DESCRIPTION

.B 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.
.br
.B 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.
.B dnet_endnode()
ends the search. It must be called when you have finished 
with this group of functions or a memory leak will result.


.SH EXAMPLE
.nf

#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);

}
