[Boost-users] [asio] multiple simultaneous async_read calls

Hello, all,

If i write some code like this:

boost::asio::async_read(socket_, bosot::asio::buffer(buffer1_.data(), len1,
handler1);
boost::asio::async_read(socket_, boost::asio::buffer(buffer2_.data(), len2,
handler2);

Will asio guarantee len1 bytes received by the first async_read, then
schedule async_read2?

or the result is undefined(like several bytes filled into buffer1, then
next several bytes into buffer, then next several bytes into buffer1)?

if the result is undefined, why asio don't add a check here?

Thanks all in advance!
