The short answer is no: CURL is a C library, so it doesn't know anything
about C++ member functions.

Yet, you can overcome this limitation with a relative ease using a
static member function that is passed a pointer to the class:

// f is the pointer to your object.
static YourClass::staticFunction(void *buffer, size_t size, size_t
nmemb, void *f)
{
   // Call non-static member function.
   static_cast<YourClass*>(f)->nonStaticFunction();
}

// This is how you pass pointer to the static function:

        curl_easy_setopt(hcurl, CURLOPT_WRITEFUNCTION,
YourClass:staticFunction);
        curl_easy_setopt(hcurl, CURLOPT_WRITEDATA, this);
