That pointer is even nicer set with CURLOPT_READDATA...

An alternative approach to this, is to use CURLOPT_POSTFIELDS to set a string,
and then use CURLOPT_CUSTOMREQUEST to set a "PUT" instead of POST. Possibly
you'd also want to change/disable the content-type and expect headers if you
go with this approach.
