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.
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
None
PROTOCOLS
FTP, HTTP and MQTT
EXAMPLE
int main(void)
{
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);
}
}
AVAILABILITY
Always
RETURN VALUE
Returns CURLE_OK
