Are you saying that you can post from a FILE * but not from a memory area? In
that case, I really must ask you to show us the relevant pieces of the code
that sets up libcurl for this... It really is no difference in the eyes of
the library.

Also, CURLOPT_POSTFIELDS is the regular way to post using a memory location.
It doesn't even need a read callback, which is fine if you have all the data
already available.

You could show us the basic functionality, with host names, paths, user name
and password replaced to something anonymous.
