.TH DNET_GETNODE 3 "April 3, 1999" "DECnet database functions"
.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
.sp
.B void *dnet_getnode (void)
.br
.B char *dnet_nextnode (void *)
.br
.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.
.bt
.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);
}
.fi
