Write a "C" function that serves as a wrapper function, and use
CURLOPT_WRITEFUNCTION and CURLOPT_WRITEDATA, and given your wrapper
function to the former, and a pointer to your class object to the
latter. Then call the member function on the class object from within
the wrapper function. I am assuming that having a static member
function without the notion of "this" is not what you're after.
