16 Buffers [buffer]

16.8 Function buffer_size [buffer.size]

template<class ConstBufferSequence> size_t buffer_size(const ConstBufferSequence& buffers) noexcept;

1

Returns: The total size of all buffers in the sequence, as if computed as follows: 

size_t total_size = 0;
auto i = std::experimental::net::buffer_sequence_begin(buffers);
auto end = std::experimental::net::buffer_sequence_end(buffers);
for (; i != end; ++i){
  const_buffer b(*i);
  total_size += b.size();
}
return total_size;
