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 an 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 +.nf +CURL *curl = curl_easy_init(); +if(curl) { + /* we want to use our own read function */ + curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_callback); + + /* enable uploading */ + curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L); + + /* specify target */ + curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/dir/to/newfile"); + + /* now specify which pointer to pass to our callback */ + curl_easy_setopt(curl, CURLOPT_READDATA, hd_src); + + /* Set the size of the file to upload */ + curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, (curl_off_t)fsize); + + /* Now run off and do what you've been told! */ + curl_easy_perform(curl); +} +.fi +.SH AVAILABILITY +Always +.SH RETURN VALUE +Returns CURLE_OK +.SH "SEE ALSO" +.BR CURLOPT_PUT "(3), " CURLOPT_READFUNCTION "(3), " +.BR CURLOPT_INFILESIZE_LARGE "(3), " |
