CURLOPT_POSTFIELDSIZE_LARGE(3)                        curl_easy_setopt options

NAME
       CURLOPT_POSTFIELDSIZE_LARGE - size of POST data pointed to

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDSIZE_LARGE,
                                 curl_off_t size);

DESCRIPTION
       If you want to post data to the server without having libcurl do a
       strlen() to measure the data size, this option must be used. When this
       option is used you can post fully binary data, which otherwise is
       likely to fail. If this size is set to -1, the library will use
       strlen() to get the size.

DEFAULT
       -1

PROTOCOLS
       HTTP(S)

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         const char *data = large_chunk;
         curl_off_t length_of_data; /* set somehow */

         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

         /* size of the POST data */
         curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE_LARGE, length_of_data);

         curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);

         curl_easy_perform(curl);
       }

AVAILABILITY
       Along with HTTP

RETURN VALUE
       Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
