示例1: append
void MessageQueue::append(In& stream)
{
unsigned usedSize,
numberOfMessages;
stream >> usedSize >> numberOfMessages;
// Trying a direct copy. This is hacked, but fast.
char* dest = numberOfMessages == (unsigned) -1 ? 0 : queue.reserve(usedSize - MessageQueueBase::headerSize);
if(dest)
{
stream.read(dest - MessageQueueBase::headerSize, usedSize);
queue.numberOfMessages += numberOfMessages;
queue.usedSize += usedSize;
queue.writePosition = 0;
}
else // Not all messages fit in there, so try step by step (some will be missing).
for(unsigned i = 0; numberOfMessages == (unsigned) -1 ? !stream.eof() : i < numberOfMessages ; ++i)
{
unsigned char id = 0;
unsigned int size = 0;
stream >> id;
stream.read(&size, 3);
char* dest = numberOfMessages != (unsigned) -1 || id < numOfDataMessageIDs ? queue.reserve(size) : 0;
if(dest)
{
stream.read(dest, size);
out.finishMessage(MessageID(id));
}
else
stream.skip(size);
}
}示例2: transfer
void transfer(In& in, cyclic_buffer<capacity>& buf) {
if (!buf.isFull()) {
size_t availSpace = std::min(buf.availableSpace(), TRANSFER_CHUNK_SIZE);
char buffer[TRANSFER_CHUNK_SIZE];
size_t numRead = in.read(buffer, availSpace);
buf.write(buffer, numRead);
}
