NAME

       CURLOPT_MAXFILESIZE - maximum file size allowed to download

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXFILESIZE, long size);

DESCRIPTION

       Pass a long as parameter. This specifies the maximum accepted size (in bytes) of a file to
       download. If the file requested is found larger than this value, the transfer  is  aborted
       and CURLE_FILESIZE_EXCEEDED is returned.  Passing a zero size disables this, and passing a
       negative size yields a CURLE_BAD_FUNCTION_ARGUMENT.

       The file size is not always known prior to the download start, and for such transfers this
       option has no effect - even if the file transfer eventually ends up being larger than this
       given limit.

       If you want a limit above 2GB, use CURLOPT_MAXFILESIZE_LARGE(3).

       Since 8.4.0, this option also stops ongoing transfers if they reach this threshold.

DEFAULT

       0, meaning disabled.

         if(curl) {
           CURLcode ret;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           /* refuse to download if larger than 1000 bytes! */
           curl_easy_setopt(curl, CURLOPT_MAXFILESIZE, 1000L);
           ret = curl_easy_perform(curl);
         }
       }
