Name

CURLOPT_POSTFIELDSIZE - size of POST data pointed to

Synopsis

Description

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, "https://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.
