multi threads using flag

I want source code to the multi threads
like this example using flag
using c++ Builder3.
thread1:-
// execute

for(;;)
{
statements
passing flag to another thread
(thread2)to resume;

}
thread2:
//execute
for(;;)
{
wait until thread1 passing flag to resume
statements
suspend
}

In thread one:
hEvent = CreateEvent( NULL, TRUE, FALSE, NULL);

for( ; ; )
{
// whenever you are ready for thread 2 to pause
::ResetEvent( hEvent );

// whenever you are ready for thread 2 to run:
::SetEvent( hEvent );
}

In thread two do this:

for( ; ; )
{
//Pauses until ::SetEvent( ) is called
::WaitForSingleObject( hEvent );
}

so in thread 1 any time you call ResetEvent( ) thread 2 will stop on that ::WaitForSingleObject call until ::SetEvent( ) gets called again
