Presumably, WriteMemoryCallback is a non-static method on your getHtml object.
libcurl doesn't know what to do with C++ methods, so you have to pass in a
C function pointer instead (or, perhaps, a static C++ method pointer).
You would then pass the 'this' pointer into CURLOPT_WRITEDATA and your
C function would then cast that back to an object and call the
WriteMemoryCallback method on that.
There is a C++ binding to libcurl available called cURLpp that may make your
life easier as it hides libcurl's C nature from you. See
