The \fICURLOPT_READDATA(3)\fP and \fICURLOPT_INFILESIZE(3)\fP or \fICURLOPT_INFILESIZE_LARGE(3)\fP options are also interesting for uploads. If the protocol is HTTP, uploading means using the PUT request unless you tell libcurl otherwise. Using PUT with HTTP 1.1 implies the use of a "Expect: 100-continue" header. You can disable this header with \fICURLOPT_HTTPHEADER(3)\fP as usual. If you use PUT to a HTTP 1.1 server, you can upload data without knowing the size before starting the transfer if you use chunked encoding. You enable this by adding a header like "Transfer-Encoding: chunked" with \fICURLOPT_HTTPHEADER(3)\fP. With HTTP 1.0 or without chunked transfer, you must specify the size. .SH DEFAULT 0, default is download .SH PROTOCOLS Most .SH EXAMPLE TODO .SH AVAILABILITY Always .SH RETURN VALUE Returns CURLE_OK .SH "SEE ALSO" .BR CURLOPT_PUT "(3), " CURLOPT_READFUNCTION "(3), " .BR CURLOPT_INFILESIZE_LARGE "(3), "
