23: .TH CURLOPT_POSTFIELDSIZE 3 "March 23, 2020" "libcurl 7.70.0" "curl_easy_setopt options"
24:
25: .SH NAME
26: CURLOPT_POSTFIELDSIZE \- size of POST data pointed to
27: .SH SYNOPSIS
28: #include <curl/curl.h>
29:
30: CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDSIZE, long size);
31: .SH DESCRIPTION
32: If you want to post data to the server without having libcurl do a strlen() to
33: measure the data size, this option must be used. When this option is used you
34: can post fully binary data, which otherwise is likely to fail. If this size is
35: set to -1, the library will use strlen() to get the size.
36:
37: If you post more than 2GB, use \fICURLOPT_POSTFIELDSIZE_LARGE(3)\fP.
38: .SH DEFAULT
39: -1
40: .SH PROTOCOLS
41: HTTP
42: .SH EXAMPLE
43: .nf
44: CURL *curl = curl_easy_init();

46: const char *data = "data to send";
47:
48: curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
49:
50: /* size of the POST data */
51: curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, (long) strlen(data));
52:
53: curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);
54:
55: curl_easy_perform(curl);
