.TH CURLOPT_MAXFILESIZE 3 "May 30, 2017" "libcurl 7.70.0" "curl_easy_setopt options"

.SH NAME
CURLOPT_MAXFILESIZE \- maximum file size allowed to download
.SH SYNOPSIS
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXFILESIZE, long size);
.SH DESCRIPTION
Pass a long as parameter. This allows you to specify the maximum \fIsize\fP
(in bytes) of a file to download. If the file requested is found larger than
this value, the transfer will not start and \fICURLE_FILESIZE_EXCEEDED\fP 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.

If you want a limit above 2GB, use \fICURLOPT_MAXFILESIZE_LARGE(3)\fP.
.SH DEFAULT
None
.SH PROTOCOLS
FTP and HTTP
.SH EXAMPLE

CURL *curl = curl_easy_init();
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);
}
