CURLOPT_NOPROGRESS - switch off the progress meter

#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 will also prevent the CURLOPT_XFERINFOFUNCTION(3) or CURLOPT_PROGRESSFUNCTION(3) from getting called.

1, meaning it normally runs without a progress meter.

curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* enable progress meter */
curl_easy_setopt(curl, CURLOPT_NOPROGRESS, 0L);
/* Perform the request */
curl_easy_perform(curl); }
