C++ (Cpp) length_storage Examples

Example #1

File: tsClient.cpp Project: amitprat/IMSDEV

int tsClient :: length()
{
    unsigned char* bufLength = new unsigned char[4];
    memset(bufLength,0,4);
    memcpy(bufLength,buffer,4);
    Storage length_storage(bufLength,4);
    int NN = length_storage.readInt() - 4;
    delete[] bufLength;
    return NN;
}

Example #2

File: socket-ns3.cpp Project: haddyclipk/ICS

bool
SocketNs3::
receiveExact(StorageNs3 &msg)
throw(SocketException)
{
    /* receive length of vector */
    unsigned char* bufLength = new unsigned char[4];
    int bytesRead = 0;
    int readThisTime = 0;

    while (bytesRead<4) {
        readThisTime = recv(socket_, (char*)(bufLength + bytesRead), 4-bytesRead, 0);

        if (readThisTime <= 0)
            BailOnSocketError("tcpip::SocketNs3::receive() @ recv");

        bytesRead += readThisTime;
