docs/libcurl: improve easy setopt examples

- always assign the curl_easy_perform() return code (and declare
  the necessary 'result' variable for it)

- always call curl_easy_cleanup() on the created easy handles

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 also prevents the CURLOPT_XFERINFOFUNCTION(3) or CURLOPT_PROGRESSFUNCTION(3) from getting called.

DEFAULT

1, meaning it normally runs without a progress meter.

%PROTOCOLS%

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

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

    /* Perform the request */
    result = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}

%AVAILABILITY%

RETURN VALUE

curl_easy_setopt(3) returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
