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);
}
