Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

NAME
CURLOPT_INFILESIZE - size of the input file to send off
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INFILESIZE, long filesize);
DESCRIPTION
When uploading a file to a remote site, filesize should be used to tell libcurl what the expected size of the input file is. This value must be passed as a long. See also CURLOPT_INFILESIZE_LARGE(3) for sending files larger than 2GB.
For uploading using SCP, this option or CURLOPT_INFILESIZE_LARGE(3) is mandatory.
To unset this value again, set it to -1.
Using CURLOPT_UPLOAD(3) to an HTTP/1.1 server and this value set to -1, makes libcurl do a chunked transfer-encoded upload.
When sending emails using SMTP, this command can be used to specify the optional SIZE parameter for the MAIL FROM command.
This option does not limit how much data libcurl actually sends, as that is controlled entirely by what the read callback returns, but telling one value and sending a different amount may lead to errors.
DEFAULT
Unset
EXAMPLE
#define FILE_SIZE 12345L
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
long uploadsize = FILE_SIZE;
curl_easy_setopt(curl, CURLOPT_URL,
"ftp://example.com/destination.tar.gz");
curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);
curl_easy_setopt(curl, CURLOPT_INFILESIZE, uploadsize);
curl_easy_perform(curl);
}
}
AVAILABILITY
SMTP support added in 7.23.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
