You use CURLOPT_POSTFIELDS or you set a read callback. This is documented and
there are several examples showing both ways used. Since the data seems binary
(includes zeroes) you need to set CURLOPT_POSTFIELDSIZE if you don't use a
read callback.

You're not asking us for how to generate the specific content you want to post
right? That has nothing to do with (lib)curl's functions or functionality.
