c++ - async_read_some return -


is there way in boost::asio know if async_read_some wont return in particular time period call function without closing socket? async_read_some() wont return if there no more data transfered buffer.

 _socket->async_read_some(      boost::asio::buffer(this->reply, sizeof(this>reply)),      boost::bind(          &tcp_ip_connection::dataprocess,          this,          boost::asio::placeholders::error,          boost::asio::placeholders::bytes_transferred      )  );

async_read_some returns immediately.

if you're talking handler (callback), if close socket before returns, think handler gets called asio::error::operation_aborted. if handle scenario maybe don't need worry if you're connected or not.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
