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. For protocols where the size is not known in advance (including FTP and HTTP) this option has no effect even if the file transfer ends up being larger than the given limit. .SH DEFAULT None .SH PROTOCOLS FTP, HTTP and MQTT .SH EXAMPLE .nf CURL *curl = curl_easy_init(); if(curl) { CURLcode ret; curl_off_t ridiculous = 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); } .fi .SH AVAILABILITY Added in 7.11.0 .SH RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. .SH "SEE ALSO" .BR CURLOPT_MAXFILESIZE "(3), " CURLOPT_MAX_RECV_SPEED_LARGE "(3), "
