23: .TH CURLOPT_POSTFIELDSIZE_LARGE 3 "March 23, 2020" "libcurl 7.70.0" "curl_easy_setopt options"
24:
25: .SH NAME
26: CURLOPT_POSTFIELDSIZE_LARGE \- size of POST data pointed to
27: .SH SYNOPSIS
28: .nf
29: #include <curl/curl.h>
30:
31: CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDSIZE_LARGE,
32: curl_off_t size);
33: .SH DESCRIPTION
34: If you want to post data to the server without having libcurl do a strlen() to
35: measure the data size, this option must be used. When this option is used you
36: can post fully binary data, which otherwise is likely to fail. If this size is
37: set to -1, the library will use strlen() to get the size.
38: .SH DEFAULT
39: -1
40: .SH PROTOCOLS
41: HTTP(S)
42: .SH EXAMPLE
43: .nf
44: CURL *curl = curl_easy_init();
45: if(curl) {
46: const char *data = large_chunk;
47: curl_off_t length_of_data; /* set somehow */
48:
49: curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
50:
51: /* size of the POST data */
52: curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE_LARGE, length_of_data);
53:
54: curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);
55:
56: curl_easy_perform(curl);
57: }
58: .fi
59: .SH AVAILABILITY
60: Along with HTTP
61: .SH RETURN VALUE
62: Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
