Jay Satiro 9a6f974881 docs: change max-filesize caveat again
- Add protocols field to max-filesize.d.

- Revert wording on unknown file size caveat and do not discuss specific
  protocols in that section.

Partial revert of ecf0225. All max-filesize options now have the list of
protocols and it's clearer just to have that list without discussing
specific protocols in the caveat.

.TH CURLOPT_MAXFILESIZE 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_MAXFILESIZE \- maximum file size allowed to download
.SH SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXFILESIZE, long size);
.SH DESCRIPTION
Pass a long as parameter. 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.
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 \fICURLOPT_MAXFILESIZE_LARGE(3)\fP.
.SH DEFAULT
None
.SH PROTOCOLS
FTP, HTTP and MQTT
.SH EXAMPLE
.nf
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
