Re: NotifyAddrChange()

Well, it's a sample... Sample code should never make its way
into production code. In this particular case the sample exits
right away so any leaks will be reclaimed by the OS right away.
You can copy the code in your test and fix the leaks yourself.

I don't understand why the NotifyAddrChange() sample code doesn't
cleanup up the events that are created. I want to put this sample code
in a loop to stress a DCHP server without leaking handles:

#include <winsock2.h>
#include <windows.h>
#include <iphlpapi.h>
#include <stdio.h>

void main()
{
OVERLAPPED overlap;
DWORD ret;

HANDLE hand = WSACreateEvent();
overlap.hEvent = WSACreateEvent();

ret = NotifyAddrChange(&hand, &overlap);

if (ret != NO_ERROR)
{
if (WSAGetLastError() != WSA_IO_PENDING)
{
printf("NotifyAddrChange error...%d\n", WSAGetLastError());
return;
}
}

if ( WaitForSingleObject(overlap.hEvent, INFINITE) == WAIT_OBJECT_0 )
printf("IP Address table changed..\n");
}

Thanks
