Yes, take a look at boost::asio::windows::random_access_handle and
random_access_handle_service.  You can use this in normal calls to
async_read, async_write, etc

Hi,<br>
In Windows we can open and read storage meidias by using the call CreateFile() and \
ReadFile() respecively. The device name is passed as a string to the CreateFile() \
call, as an example &quot;PhysicalDrive1&quot;. Create file returns  a handle of type \
&quot;HANDLE&quot;. can I use this handle in asio in order to read a device file?<br> \
</blockquote></div><br>Yes, take a look at boost::asio::windows::random_access_handle \
and random_access_handle_service.  You can use this in normal calls to async_read, \
async_write, etc<br>
