CURLOPT_MAXFILESIZE_LARGE(3)

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 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.

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.

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

DEFAULT
None

PROTOCOLS
FTP, HTTP and MQTT

EXAMPLE
int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode ret;
    curl_off_t ridiculous = (curl_off_t)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.
