CURLOPT_POSTFIELDSIZE(3)   curl_easy_setopt options   CURLOPT_POSTFIELDSIZE(3)




NAME

       CURLOPT_POSTFIELDSIZE - size of POST data pointed to


SYNOPSIS

       #include <curl/curl.h>

       CURLcode  curl_easy_setopt(CURL  *handle,  CURLOPT_POSTFIELDSIZE,  long
       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.

       If you post more than 2GB, use CURLOPT_POSTFIELDSIZE_LARGE(3).


DEFAULT

       -1


PROTOCOLS

       HTTP


EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         const char *data = "data to send";

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

         /* size of the POST data */
         curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, (long) strlen(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.
