curl_easy_getinfo options                  CURLINFO_CONTENT_LENGTH_DOWNLOAD(3)



NAME
       CURLINFO_CONTENT_LENGTH_DOWNLOAD - get content-length of download

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_LENGTH_DOWNLOAD,
                                  double *content_length);

DESCRIPTION
       Pass  a  pointer to a double to receive the content-length of the down‐
       load. This is the value read  from  the  Content-Length:  field.  Since
       7.19.4, this returns -1 if the size is not known.

       CURLINFO_CONTENT_LENGTH_DOWNLOAD_T(3)   is  a  newer  replacement  that
       returns a more sensible variable type.

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

         /* Perform the request */
         res = curl_easy_perform(curl);

         if(!res) {
           /* check the size */
           double cl;
           res = curl_easy_getinfo(curl, CURLINFO_CONTENT_LENGTH_DOWNLOAD, &cl);
           if(!res) {
             printf("Size: %.0f\n", cl);
           }
         }
       }
