Get the total number of bytes in a buffer sequence.
template< typename BufferSequence> std::size_t buffer_size( const BufferSequence & b);
The buffer_size
function determines the total size of all buffers
in the buffer sequence, as if computed as follows:
size_t total_size = 0; auto i = asio::buffer_sequence_begin(buffers); auto end = asio::buffer_sequence_end(buffers); for (; i != end; ++i) { const_buffer b(*i); total_size += b.size(); } return total_size;
The BufferSequence
template parameter may meet either of the
ConstBufferSequence
or MutableBufferSequence
type
requirements.
