NAME

6       CURLOPT_POSTFIELDSIZE_LARGE - size of POST data pointed to
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDSIZE_LARGE,
12                                 curl_off_t size);
13

DESCRIPTION

15       If  you  want  to  post  data to the server without having libcurl do a
16       strlen() to measure the data size, this option must be used. When  this
17       option  is  used  you  can  post  fully binary data, which otherwise is
18       likely to fail. If this size  is  set  to  -1,  the  library  will  use
19       strlen() to get the size.
20

DEFAULT

22       -1

PROTOCOLS

EXAMPLE

31         curl_off_t length_of_data; /* set somehow */
32
33         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
34
35         /* size of the POST data */
36         curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE_LARGE, length_of_data);
37
38         curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);
