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.
