Jason Nye pointed out that callbacks don't need to use the "C namespace"

There's basically only one thing to keep in mind when using C++ instead of C

when interfacing libcurl:

 "The Callbacks Must Be Plain C"

The callbacks CANNOT be non-static class member functions

So if you want a write callback set in libcurl, you should put it within

\&'extern'. Similar to this:

Example C++ code:

.nf

 extern "C" {

    size_t write_data(void *ptr, size_t size, size_t nmemb,

class AClass {

    static size_t write_data(void *ptr, size_t size, size_t nmemb,

                             void *ourpointer)

    {

      /* do what you want with the data */

 }

.fi

This will of course effectively turn the callback code into C. There won't be

any "this" pointer available etc.

.SH "Proxies"

What "proxy" means according to Merriam-Webster: "a person authorized to act
