This specifies the maximum accepted \fIsize\fP (in bytes) of a file to download. If the file requested is found larger than this value, the transfer is aborted and \fICURLE_FILESIZE_EXCEEDED\fP 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 \fICURLOPT_MAXFILESIZE_LARGE(3)\fP. Since 8.4.0, this option also stops ongoing transfers if they reach this threshold. .SH DEFAULT None .SH PROTOCOLS FTP, HTTP and MQTT .SH EXAMPLE .nf 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); } } .fi .SH AVAILABILITY Always .SH RETURN VALUE Returns CURLE_OK .SH "SEE ALSO" .BR CURLOPT_MAX_RECV_SPEED_LARGE (3), .BR CURLOPT_MAXFILESIZE_LARGE (3)
