暂停进程

 

暂停/恢复 某个进程的所有线程 :

void suspendProcess(DWORD pid, BOOL bSuspend)
{
    HANDLE snap = CreateToolhelp32Snapshot( TH32CS_SNAPTHREAD, pid );
    if(snap == INVALID_HANDLE_VALUE){
        return;
    }
    THREADENTRY32 th32;
    th32.dwSize = sizeof(THREADENTRY32);
    if(!Thread32First (snap,&th32))
    {
        CloseHandle(snap);
        return;
    }
    do
    {
        if(th32.th32OwnerProcessID == pid)
        {
            HANDLE hTh = OpenThread(THREAD_SUSPEND_RESUME,FALSE,th32.th32ThreadID);
            if(hTh){
                if(bSuspend)
                    SuspendThread(hTh);
                else
                    ResumeThread(hTh);
            }
           CloseHandle(hTh);
        }
    }while(Thread32Next(snap,&th32));
    CloseHandle(snap);
}
