DNET_GETNODE(3)
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); - }
