CURLOPT_POSTFIELDSIZE_LARGE(3)      libcurl     CURLOPT_POSTFIELDSIZE_LARGE(3)




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 static 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, libcurl uses strlen() to get
       the size or relies on the CURLOPT_READFUNCTION(3) (if used) to signal
       the end of data.


DEFAULT

       -1


PROTOCOLS

       HTTP(S)


EXAMPLE

       extern char *large_chunk; /* pointer to somewhere */

       int main(void)
       {
         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.
