in reply to Decode perl cgi response in C

By 'receive "Download" when I post to the cgi.... ' do you -- by any chance -- mean that when you do some sort of submit that you are prompted to "Download" something -- as, for example, your cgi script?

If so, you may have a permissions problem or a mis-configured Apache or cgi-bin.

If I've misconstrued your question or the logic needed to answer it, I offer my apologies to all those electrons which were inconvenienced by the creation of this post.

    Yes...I think what it is telling me is to download a small file containing the text response. I tried an example in firefox and I got a prompt...Do you want to download test2.cgi? When I downloaded the file, it contained the desired text. "Hello". With my embedded system, I don't want to download a file...I just want to read the text it contains. Is that possible? I have a small perl client that just prints the response, so I would like to replicate this in C.

      Maybe you want to learn about "sockets"? I assume that Unix Network Programming still is the authoritative book about this.

      Basically, a "socket" is like a "file", except you can't seek on it, and it goes over the network. From C, you can read/write the socket and you only need to know about the protocol that is spoken over that socket.

      The basic idea is that "download data" vs. "read data" is only a frontend issue and exists only for users, not for programs.

[Corion]: I haven't found a good way to include/use the source SVGs I use for creating the PNGs directly as animations
[ambrus]: Presentations come in many different shapes, and so slides do as well.
[Corion]: Doing that in Powerpoint or Ooxml would be nice(r) but I'm much quicker doing the outline of a presentation and the code as Pod
[Corion]: Hurrr - on a machine that is behaving weirdly, I have two processes CROND running. I guess that is the source of unattended jobs sometimes not finding their files anymore...
[ambrus]: Most of the time if I make slides, they're just a formatted document with a medium level of formality (between a well written article and an informal draft), with usually the page breaks chosen carefully and possibly some content repeated between pages.
[Corion]: ambrus: My slides are mostly a list of things I want to talk about. But sometimes I want to point out interesting parts, or build up a larger image from small components. This is where animations/ highlights would come in well
[choroba]: what I like about slides in HTML + CSS is I can use templates to produce them, which means all code in slides is tested, and I can version them in git
[ambrus]: Btw, a request to everyone who organizes international conferences where presenters will show slides.
[ambrus]: In the document where you tell people how long the presentations are supposed to be, please also tell the aspect ratio of your projectors, because that's not obvious in advance.
[Corion]: ambrus: A more important point is that when constructing slides, you should respect a margin around your slide content of maybe 10% where no important information should be ;)
