CURLOPT_MAXFILESIZE - maximum file size allowed to download
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXFILESIZE, long size);
Pass a long 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.
If you want a limit above 2GB, use
CURLOPT_MAXFILESIZE_LARGE(3).
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);
}
CURLOPT_MAXFILESIZE_LARGE(3), CURLOPT_MAX_RECV_SPEED_LARGE(3),
