Erstellen Prozess funktioniert nicht

Question

Ich bin ein Verfahren zu schaffen und viele Kernel-Objekte Anforderung an das System zu machen. Mein Code ist, dass:

int main(){
    //Cria processo para o Data Viewer Unit
        LPSTARTUPINFOA si;
    PROCESS_INFORMATION pi;

    // Start the child process. 
    if(!CreateProcessA( 
                "E:\\Documents\\Faculdade\\Matérias\\Automação em Tempo Real\\TP 3\\DataViewerUnit\\Debug\\DataViewerUnit.exe", // Module name
                NULL,                                   // Command line
                NULL,                                   // Process handle not inheritable
                NULL,                                   // Thread handle not inheritable
                FALSE,                              // Set handle inheritance to FALSE
                CREATE_NEW_CONSOLE,   // No creation flags
                NULL,                                   // Use parent's environment block
                NULL,                                   // Use parent's starting directory 
                si,                                     // Pointer to STARTUPINFO structure
                &pi )                                   // Pointer to PROCESS_INFORMATION structure
    ) 
    {
        printf( "CreateProcess failed (%d).\n", GetLastError() );
        return 0;
    }

  // Wait until child process exits.
  WaitForSingleObject( pi.hProcess, INFINITE );

    LOG("Traffic System initiating...");
    LOG("Keyboard commands:\n"
        "0              - Changes the system mode to manual.\n"
        "1              - Changes the system mode to automatic.\n"

        );

    system("PAUSE");
    isAutoMode = TRUE;
    terminate_progam = FALSE;
    terminate_TOU = FALSE;
    bufferSpace = BUFFER_SIZE;
    InitializeCriticalSection(&bufferCS);
    system("PAUSE");
    hMailslot = CreateFile(MAILSLOT, GENERIC_WRITE, FILE_SHARE_READ, 
        NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
    ASSERT(hMailslot, "Mailslot couldn't be created");

    hHasPosition = CreateSemaphore(NULL, BUFFER_SIZE, BUFFER_SIZE,

    ASSERT(hTimer, "Timer semaphore couldn't be created.");

    nextMsgToRead = 0;
    nextPositionToWrite = 0;

    for (int i = 0;i < RU_QUANTITY;i++) {
        hRUs[i] = (HANDLE) _beginthreadex(NULL, 0, (CAST_FUNCTION)RUAction, (LPVOID)i, 0, NULL);
        ASSERT(hRUs[i], "RU " << i << "could not be created.");
        DEBUG("RU " << i << " created.");
        RUTime[i] = generateTime(100, 200);
    DEBUG("Remote Unit " << i << " interval: " <<
        RUTime[i]);
    }

    HANDLE hTOU = (HANDLE) _beginthreadex(NULL, 0, (CAST_FUNCTION)TOUAction, NULL, 0, NULL);
    ASSERT(hTOU, "Traffic Optimization Unit couldn't be created.");

    bool isLocked = false;
    int typed;
    do{
        typed = _getch();
        switch(typed){
        case CHAR0:         
            if(isAutoMode)
                LOG("You changed the mode to manual.")
            else
                LOG("Mode is already manual.")
                isAutoMode = false;
            break;
        case CHAR1:         
            if(!isAutoMode)
                LOG("You changed the mode to automatic.")
            else
                LOG("Mode is already automatic.")
            isAutoMode = true;
            break;
        case SPACEBAR :
            if(isLocked){
                isLocked = false;
                SetEvent(hBufferLockStatus);
                LOG("You unlocked the buffer.");
            } else {
                isLocked = true;
                ResetEvent(hBufferLockStatus);
                LOG("You locked the buffer.");
            }
            break;
        Default:
            break;
        }
    } while (typed!=ESC);
    LOG("You typed ESC, the program will be finished.");
    //Pede o fim das threads

    terminate_progam = true;
    // Importante para que as threads não fiquem 
    // travadas sem poder terminar.
    SetEvent(hBufferLockStatus);
    WaitForMultipleObjects(RU_QUANTITY, hRUs, TRUE, INFINITE);
    terminate_TOU = true;
    WaitForSingleObject(hTOU, INFINITE);


    // Close process and thread handles. 
  CloseHandle(pi.hProcess);
  CloseHandle(pi.hThread);
    CloseHandle(hHasMsg);
    CloseHandle(hHasPosition);
    CloseHandle(hBufferLockStatus);
    CloseHandle(hTimer);

    return 0;
}

Ich habe fast all diesen Code kommentiert und erstellen Prozess läuft ok. Wenn ich mehr als 1 Kernel-Objekt verlassen, stoppt das Programm laufen und Windows Vista zeigt eine Meldung „Dieses Programm Stopp zu laufen ...“. Der andere Prozess hat nur ein cout etwas zu sagen ...

Ich möchte wissen, was mit meinem Code falsch ist. Grüße, Leandro Lima

Answer 1

Verwenden Sie Zeromemory oder Memset und initialisieren Ihre Process und Startup

Dies ist ein Zeiger auf eine Startinfo erklärt Struktur die Struktur der deklarieren und über einen Verweis in     LPSTARTUPINFOA si

gesetzt si.cb = sizeof (STARTUP)

Something Like this

PROCESS_INFORMATION PI;
STARTUPINFO SI;   
SI.dwFlags =  STARTF_USESTDHANDLES;
SI.cb = sizeof(STARTUPINFO);
char * sCommandLine = _strdup(sCommand.c_str());
if(!CreateProcess(NULL,sCommandLine,NULL,NULL,true,CREATE_NO_WINDOW,NULL,NULL,&SI,&PI))

Answer 2

Sie vorbei einen nicht initialisierten Zeiger auf eine STARTUP Struktur. Sie benötigen einen STARTUP Struktur deklarieren, initialisieren seine Felder und einen Zeiger auf sie übergeben.
