boost::asio::buffer + std::wstring
Hi, I'm sending unicode text over a socket using boost::asio::async_write and boost::asio::buffer however only 1/4 of the string ends up at the receiver. What must I do so that all bytes are sent? Thanks!
"content", etc are std::wstring objects. std::vectorboost::asio::const_buffer reply::to_buffers() { std::vectorboost::asio::const_buffer buffers; buffers.push_back(status_strings::to_buffer(status)); buffers.push_back(boost::asio::buffer(misc_strings::crlf)); buffers.push_back(boost::asio::buffer(content)); return buffers; } and ... request_handler_.handle_request(req, reply_); boost::asio::async_write(socket_, reply_.to_buffers(), strand_.wrap( boost::bind(&connection::handle_write, shared_from_this(), _1)) );

Please, don't top-tpost.
"content", etc are std::wstring objects.
Are you sure they outlive the async operation (eg. aren't they local objects)?
std::vectorboost::asio::const_buffer reply::to_buffers() { std::vectorboost::asio::const_buffer buffers;
buffers.push_back(status_strings::to_buffer(status)); buffers.push_back(boost::asio::buffer(misc_strings::crlf)); buffers.push_back(boost::asio::buffer(content));
return buffers; } and ... request_handler_.handle_request(req, reply_);
boost::asio::async_write(socket_, reply_.to_buffers(), strand_.wrap( boost::bind(&connection::handle_write, shared_from_this(), _1))
Check also that you don't call async_write() when another async_write() to the same socket is in progress.

Check also that you don't call async_write() when another async_write() to the same socket is in progress. The issue isn't writing nor object lifetime. If I use std::string objects the receiver gets all of the content but with std::wstring only 1/4 of the content is received. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users

It's the same buffer() function both for std::string and std::wstring:

It's the same buffer() function both for std::string and std::wstring: Right. On linux the data loss is 3/4 and on windows it's 1/2. Coincidently wchar_t is 4 bytes on linux and 2 bytes on windows. It seems as if boost::asio::buffer is treating it internally as 1 byte. :-/
