libcurl will not allow you to do multi-part formposts easily without size
limits. The multipart formpost stuff in libcurl requires that the full post
is contructed in memory before it is sent off...

I don't understand what you mean.

No, you can send away anything, including binary stuff. Whatever you please
really.

They are not. You must be confusing C with something else! ;-)

What are you working around? Why can't you just convert your working PHP
program into a C program doing the same thing? The interfaces are very
similar using either language.

I don't think you really want the CURLOPT_CRLF, or do you?

libcurl would make its own Host: header, you don't need to provide it
yourself.

This won't work. More about this:

Nope. There's nothing that prevents us to add a system to curl where this can
be modified, but:

1. Multipart formposts as defined in RFC1867 seems to have defined that
   multipart/form-data is the mime-type to use.

   Also, since the boundary string is generated and used within the formdata
   context, we can't just change it easily in the header only.

2. Since you have a pretty clear understanding and exact wishes of what you
   want to send away, why don't you just create a big pre-formatted buffer
   that looks the way you want it and do a regular POST with it? Set
   CURLOPT_POST and then provide all post-data with a normal read callback.

Yes, CURLOPT_DEBUGFUNCTION gives you the lot.
