C++ (Cpp) moveToNextElement Examples

Example #1

File: QNetworkReplyHandler.cpp Project: AaronZhangL/phantomjs

// m_formElements[0] is the current item. If the destination buffer is
// big enough we are going to read from more than one FormDataElement
qint64 FormDataIODevice::readData(char* destination, qint64 size)
{
    if (m_formElements.isEmpty())
        return -1;

    qint64 copied = 0;
    while (copied < size && !m_formElements.isEmpty()) {
        const FormDataElement& element = m_formElements[0];
        const qint64 available = size-copied;

        if (element.m_type == FormDataElement::data) {
            const qint64 toCopy = qMin<qint64>(available, element.m_data.size() - m_currentDelta);
            memcpy(destination+copied, element.m_data.data()+m_currentDelta, toCopy); 
            m_currentDelta += toCopy;
