[Help]Locator in C++/Packet 9C42

I'm working in my locator using C++, so i finish them but i don't know if will work, i copy the source of Hare and converte to C++ in my style, so the packet stuff to build the server list :

Code:

---

void Tokenize(const string& str,
                      vector<string>& tokens,
                      const string& delimiters = " ")
{
    // Skip delimiters at beginning.
    string::size_type lastPos = str.find_first_not_of(delimiters, 0);
    // Find first "non-delimiter".
    string::size_type pos    = str.find_first_of(delimiters, lastPos);

    while (string::npos != pos || string::npos != lastPos)
    {
        // Found a token, add it to the vector.
        tokens.push_back(str.substr(lastPos, pos - lastPos));
        // Skip delimiters.  Note the "not_of"
        lastPos = str.find_first_not_of(delimiters, pos);
        // Find next "non-delimiter"
        pos = str.find_first_of(delimiters, lastPos);
    }
}

string ToLower( char* szString )
{
        char szBuffer[256];

        memcpy( szBuffer, szString, strlen( szString ) );

        szBuffer[ strlen( szString ) ] = '\x00';

        for( unsigned i = 0; i < strlen( szBuffer ); i++ )
        {
                if( szBuffer[i] > 64 && szBuffer[i] < 91 )
                {
                        szBuffer[i] += 32;
                }
        }

        string sReturn = szBuffer;

        return sReturn;
}

void BuildServerList( void )
{
        /* Build server List */
        CPacket *pPacket = CPacket::CreatePacket( MPV_DECRYPT, 0x9C42 );       

        /* DO PACKTE STUFF */

        int pCount = 1, pSize = 83;
        int total = 91;
       
        vector<string> tokens;
        Tokenize( g_mConfig.sIP, tokens, "." );

        BYTE ServerType;

        string svtype = ToLower( (char*)g_mConfig.sServerType.c_str() );

        if( !strcmp( svtype.c_str(), "match" ) )
        {
                ServerType = 1;
        }
        else if( !strcmp( svtype.c_str(), "clan" ) )
        {
                ServerType = 2;
        }
        else if( !strcmp( svtype.c_str(), "test" ) )
        {
                ServerType = 3;
        }
        else if( !strcmp( svtype.c_str(), "developer" ) )
        {
                ServerType = 4;
        }
        else
        {
                ServerType = 2;
        }

        pPacket->WriteInt( 91 );
        pPacket->WriteInt( 83 );
        pPacket->WriteInt( 1 );
        pPacket->WriteByte( atoi( tokens[0].c_str() ) );
        pPacket->WriteByte( atoi( tokens[1].c_str() ) );
        pPacket->WriteByte( atoi( tokens[2].c_str() ) );
        pPacket->WriteByte( atoi( tokens[3].c_str() ) );
        pPacket->WriteByte( atoi( tokens[0].c_str() ) );
        pPacket->WriteByte( atoi( tokens[1].c_str() ) );
        pPacket->WriteByte( atoi( tokens[2].c_str() ) );
        pPacket->WriteByte( atoi( tokens[3].c_str() ) );
        pPacket->WriteInt( (int)g_mConfig.wPort );
        pPacket->WriteByte( ServerType ); // sv type
        pPacket->WriteShort( (short)g_mConfig.nServerCapacity ); // sv capacity
        pPacket->WriteShort( (short)g_nPlayerCount ); // players count
        pPacket->WriteByte( ServerType ); // sv type
        pPacket->WriteByte( 1 ); // DON't TOUCH THIS
        pPacket->WriteString( (char*)g_mConfig.sServerName.c_str(), false );

        /* AE */

        nPacketBuffer = pPacket->m_nIndex;

        pPacketBuffer = new char[nPacketBuffer];
        ZeroMemory( pPacketBuffer, nPacketBuffer );

        pPacket->FinalizePacket( pPacketBuffer );

        Log( "Montagem do packet principal finalizada, tamanho : %d", nPacketBuffer );

        delete pPacket;
}

nPacketBuffer, pPacketBuffer its global var

atoi( tokens[0].c_str() ) is like string.Split in C#

i test and not work ... so anyone can help me ?

pPacket->WriteByte( atoi( tokens[0].c_str() ) );
pPacket->WriteByte( atoi( tokens[1].c_str() ) );
pPacket->WriteByte( atoi( tokens[2].c_str() ) );
pPacket->WriteByte( atoi( tokens[3].c_str() ) );
pPacket->WriteByte( atoi( tokens[0].c_str() ) );
pPacket->WriteByte( atoi( tokens[1].c_str() ) );
pPacket->WriteByte( atoi( tokens[2].c_str() ) );
pPacket->WriteByte( atoi( tokens[3].c_str() ) );

What is that adding to the packet, because that does not look right.

and what does this do?
pPacket->FinalizePacket( pPacketBuffer );

I assume the WriteByte calls write the IP address to the packet, and the FinalizePacket call seems to fill a buffer with the finalized packet. That would probably involve calculating the checksum at that point, too.
