How to start, pause, resume, and end background work processes in VC ++

1. Create a process:

: Afxbeginthread (bkthreadproc, this-> getsafehwnd ());

2. background process functions and event variables that control thread suspension, recovery, and exit:

Cevent g_eventthreadpause (false, true );
Cevent g_eventthreadquit (false, true );

Uint bkthreadproc (lpvoid pparam)
{
Trace ("START background thread. \ n ");
While (true)
{

// Check whether the backgound thread need to quit
If (: waitforsingleobject (g_eventthreadquit, 0) = wait_object_0)
{

// Clean resource before quiting background thread
Trace ("Quit background thread. \ n ");
Break;
}

// Check whether the backgound thread need to pause

: Waitforsingleobject (g_eventthreadpause, infinite );

//.......

// Do some background work here ......

//.......

// Sleep (1, 2000 );
}

Return 0;
}

3. Thread Suspension

G_eventthreadpause.resetevent ();

4. Restore the thread

G_eventthreadpause.setevent ();

5. Exit the thread

G_eventthreadpause.setevent ();
G_eventthreadquit.setevent ();
