NAME
       CURLOPT_NOPROGRESS - switch off the progress meter

SYNOPSIS
       #include <curl/curl.h>

       CURLcode   curl_easy_setopt(CURL   *handle,   CURLOPT_NOPROGRESS,  long
       onoff);

DESCRIPTION
       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_PROGRESSFUNCTION(3) from getting called.

       Future versions of libcurl are likely to not have any built-in progress
       meter at all.

DEFAULT
       1, meaning it normally runs without a progress meter.

PROTOCOLS
       All

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

         /* enable progress meter */
         curl_easy_setopt(curl, CURLOPT_NOPROGRESS, 0L);

         /* Perform the request */
         curl_easy_perform(curl);
       }

AVAILABILITY
       Always

RETURN VALUE
       Returns CURLE_OK.
