NAME

       CURLOPT_UPLOAD - enable data upload

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_UPLOAD, long upload);

DESCRIPTION

       The  long  parameter  upload  set  to  1  tells  the  library  to  prepare for and perform an upload. The
       CURLOPT_READDATA(3) and CURLOPT_INFILESIZE(3) or CURLOPT_INFILESIZE_LARGE(3) 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 CURLOPT_HTTPHEADER(3) 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  CURLOPT_HTTPHEADER(3).  With  HTTP  1.0 or without chunked transfer, you must specify the
       size.

EXAMPLE

       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);
       }
