CURLOPT_NOPROGRESS (3) Linux Manual Page
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.
Return Value
Returns CURLE_OK.
