CURLOPT_MAXFILESIZE(3) curl_easy_setopt options CURLOPT_MAXFILESIZE(3) 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 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_FILE- SIZE_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). DEFAULT None PROTOCOLS FTP, HTTP and MQTT EXAMPLE 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 ATTRIBUTES See attributes(7) for descriptions of the following attributes: +---------------+------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+------------------+ |Availability | web/curl | +---------------+------------------+ |Stability | Uncommitted | +---------------+------------------+ SEE ALSO CURLOPT_MAXFILESIZE_LARGE(3), CURLOPT_MAX_RECV_SPEED_LARGE(3), NOTES Source code for open source software components in Oracle Solaris can be found at https://www.oracle.com/downloads/opensource/solaris-source- code-downloads.html.
