CURLOPT_NOPROGRESS

#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOPROGRESS, long onoff);

If onoff is to 1, it tells the library to shut off the progress meter completely for requests done with this handle. It also prevents the CURLOPT_XFERINFOFUNCTION(3) or CURLOPT_PROGRESSFUNCTION(3) from getting called.

1, meaning it normally runs without a progress meter.
