Copies a limited number of bytes from a source buffer sequence to a target buffer sequence.
template< typename MutableBufferSequence, typename ConstBufferSequence> std::size_t buffer_copy( const MutableBufferSequence & target, const ConstBufferSequence & source, std::size_t max_bytes_to_copy);
A modifiable buffer sequence representing the memory regions to which the bytes will be copied.
A non-modifiable buffer sequence representing the memory regions from which the bytes will be copied.
