Re: [Boost-users] Transferring files across a network.
To all those who helped, especially Rahul who very kindly made some sample code available and put me on the right track. I now have a client and a server that can handle multiple files being sent over the network. The files are attached for your interest. If anyone can improve them I really will welcome their comments. If there is a need, it is Ok to include them as examples in the ASIO documentation. I have no issues with this. Thanks once again to everyone who helped. Regards Andrew

I mentioned this before, but here goes again - the following: sizeof(buffer_) should be: buffer_.size() Alignment or padding on some compilers might cause sizeof(buffer_) to be incorrect (different than buffer_size(), although it's probably rare). Cliff

No problem! It might be that every commonly used C++ compiler has sizeof(boost::array<char, N>) == sizeof(char[N]), but unless there's a guarantee I'm missing, I could see an odd compiler that pads or aligns in some strange fashion, causing rare and hard-to-diagnose errors. Definitely you're good with (boost::array<char,N>).size() == sizeof(char[N]). Thanks for the example code - it would be good to add it (and others) to the Asio docs. Speaking of which, I know Chris K has been busy (or in poor health?) and mostly unavailable for a while - I wonder if he wouldn't mind granting someone edit access to the Asio source for documentation purposes (or minor bug fixes). There's been a wealth of knowledge shared through the Boost and Asio mail lists, such as serial IO examples and run / poll / work service explanations. Cliff
I have just modified the code so it directly reads from the file and writes to the file instead of into an iostream object. Much faster. So if someone is adding examples to the ASIO docs, I wil be glad to send them the examples. Regards Andrew On Mon, Feb 2, 2009 at 5:03 AM, Cliff Green <cliffg@codewrangler.net> wrote:

Can u send me the example just for viewing. ________________________________ From: Andrew Maclean <andrew.amaclean@gmail.com> To: boost-users@lists.boost.org Sent: Monday, 2 February, 2009 10:35:58 AM Subject: Re: [Boost-users] Transferring files across a network.

Yes, I am agree with your suggestion. Asio documentation should be updated. Several users are having good examples that can be added to documentation. -Rahul ________________________________ From: Cliff Green <cliffg@codewrangler.net> To: boost-users@lists.boost.org Sent: Sunday, 1 February, 2009 11:33:51 PM Subject: Re: [Boost-users] Transferring files across a network.

Here are the examples. I have tested them in Linux (debian, gcc-4.3.2) and Windows Vista (Visual Studio 2008) using the latest boost version. Feel free to use them. If you have any improvements, please let me know and feed back a copy to me. As I have said, I am new at this. I think it is an important and useful example. However I may be biased.
