WaitForMultipleObjects для завершения потоков

[sn0w]

вообщем простая подмена (не идеальная конечно) для WaitForMultipleObjects (когда речь идет об n потоках, причем n > MAXIMUM_WAIT_OBJECTS) и нам нужно ждать когда все они завершатся.

#include "stdafx.h"
#include <conio.h>
#include <windows.h>


DWORD g_dwThreadsCompleted;

printf("thread #%d completed\n", (int)lp);
return 0;
