Re: [libmicrohttpd] How to send Chunked messages

[silvioprog]

Hi Santos and Christian.

Santos, the Christian's answer was complete and clarified me a lot too. ☺

Christian, it seems sendfile() is not available in mingw and in the Google's NDK (Android), but my library must work at least on Windows, Linux, Raspbian and Android, so I've used the fopen() in this way: link (sorry for put a link, but the code is a little bit large). Do you recommend to use fopen() in those cases? I would like to use sendfile() because it is very fast, but I can't implement it for Windows.

Thanks in advance for your help!

Dear Santos,

MHD can send chunked response to the client. That said, this is not a
question of how large the file is. Especially, if it is simply a very
large file, MHD allows you to use sendfile() to avoid having a copy of
the data in userspace.  Chunked encoding is usually only used if the
application simply does not know the size of the response ahead of time.

Happy hacking!

Christian
