C++ (Cpp) countChainElements Examples

Example #1

File: IOBuf.cpp Project: JingangLi/folly

folly::fbvector<struct iovec> IOBuf::getIov() const {
  folly::fbvector<struct iovec> iov;
  iov.reserve(countChainElements());
  IOBuf const* p = this;
  do {
    // some code can get confused by empty iovs, so skip them
    if (p->length() > 0) {
      iov.push_back({(void*)p->data(), p->length()});
    }
    p = p->next();
  } while (p != this);
  return iov;
}

Example #2

  folly::fbvector<struct iovec> iov;
  iov.reserve(countChainElements());
  appendToIov(&iov);
  return iov;
