The code introduced in http://curl.haxx.se/libcurl/c/ftpget.html includes an error in my_fwrite function.

This function returns the value returned by fwrite. This value is nmemb.

However, the documentation of CURLOPT_WRITEFUNCTION says: "Return the number of bytes actually taken care of" this number is: "The size of the data pointed to by ptr is size multiplied with nmemb".

So my_fwrite should return (size * nmemb). After verifying that fwrite had returned the same value as nmemb.

While testing this example I have noticed that every call to my_fwrite comes with size = 1. This is the reason why the error is unnoticeable. However, it is not guaranteed to get every call with size = 1.
