Here is my code:
    CURL *d;
    d = curl_easy_init();
    fp = fopen(argv[2], "w");

    // Set libcurl options
    curl_easy_setopt(d, CURLOPT_URL, finalURL);
    curl_easy_setopt(d, CURLOPT_WRITEFUNCTION, NULL);
    curl_easy_setopt(d, CURLOPT_WRITEDATA, fp);
    curl_easy_setopt(d, CURLOPT_USERAGENT, "Mozilla/4.0");
    
    res = curl_easy_perform(d);
            
    fclose(fp);
    curl_easy_cleanup(c);

The curl_easy_setopt docs for CURLOPT_WRITEFUNCTION say: Set this option to NULL to get the internal default function. The
internal default function will write the data to the FILE * given with
CURLOPT_WRITEDATA. So shouldn't it be writing whatever it gets from finalURL to fp? Because the file pointed to by fp is completely blank no matter what the inputs to the program are. Help?
