CURLOPT_MAXFILESIZE_LARGE(3) Library Functions Manual
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. 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.
Since 8.4.0, this option also stops ongoing transfers if they reach
this threshold.
DEFAULT
0, meaning disabled.
PROTOCOLS
This functionality affects 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 curl 7.11.0
RETURN VALUE
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if
not, or CURLE_BAD_FUNCTION_ARGUMENT if the size passed is invalid.
