Is there in C API for PHP's CURLOPT_RETURNTRANSFER?

Question

In PHP API we could use curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); but how to translate it into C? I tried curl_easy_setopt(curl_handle, CURLOPT_RETURNTRANSFER, true); but failed.

Answer 1

There's no CURLOPT_RETURNTRANSFER in libcurl C API. You can do that with a callback function, it's one of libcurls examples : get a remote file in memory only .

Answer 2

I think this mailing list entry is relevant:

CURLOPT_RETURNTRANSFER was invented by the PHP binding author and is basically just a shortcut for appending all received data into a memory buffer. With the C API and basically all existing bindings as well (including the PHP one) you can use a write callback to append all data to a single buffer.
