NAME

CURLOPT_MAXFILESIZE_LARGE - maximum file size allowed to download

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXFILESIZE_LARGE,
                          curl_off_t size);

DESCRIPTION

Pass a curl_off_t as parameter. This allows you to specify the maximum size (in bytes) of a file to download. If the file requested is found larger than this value, the transfer will not start and CURLE_FILESIZE_EXCEEDED will be returned.

The file size is not always known prior to download, and for such files this option has no effect even if the file transfer ends up being larger than this given limit. This concerns both FTP and HTTP transfers.

DEFAULT

None

PROTOCOLS

FTP and HTTP

EXAMPLE

CURL *curl = curl_easy_init();
if(curl) {
  CURLcode ret;
  curl_off_t ridiculous = 1 << 48;
  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
  /* refuse to download if larger than ridiculous */
  curl_easy_setopt(curl, CURLOPT_MAXFILESIZE_LARGE, ridiculous);
  ret = curl_easy_perform(curl);
}

AVAILABILITY

Added in 7.11.0

RETURN VALUE

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
