Hello. I'm implementing a server and a client in boost.asio, and I would like to know the differences between:
- socket::send() and socket::write_some
- socket::receive() and socket::read_some
In the documentation, for what I read, they look like they do the same thing. Can anyone explain me the difference? Thanks.
There are different overloads of both. The overloads that take a single parameter of ConstBufferSequence do exactly the same thing: template <typename ConstBufferSequence> std::size_t send(const ConstBufferSequence& buffers) { boost::system::error_code ec; std::size_t s = this->service.send(this->implementation, buffers, 0, ec); boost::asio::detail::throw_error(ec); return s; } template <typename ConstBufferSequence> std::size_t write_some(const ConstBufferSequence& buffers) { boost::system::error_code ec; std::size_t s = this->service.send(this->implementation, buffers, 0, ec); boost::asio::detail::throw_error(ec); return s; } "write_some" is a part of SyncWriteStream concept. I don't know why "send" is needed, maybe it's just for backward compatibility.
