.TH CURLOPT_POSTFIELDSIZE_LARGE 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_POSTFIELDSIZE_LARGE \- size of POST data pointed to
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDSIZE_LARGE,
curl_off_t size);
.SH 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.
.SH DEFAULT
-1
.SH PROTOCOLS
HTTP(S)
.SH EXAMPLE
.nf
CURL *curl = curl_easy_init();
if(curl) {
const char *data = large_chunk;
curl_off_t length_of_data; /* set somehow */
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* size of the POST data */
curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE_LARGE, length_of_data);
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);
curl_easy_perform(curl);
}
.fi
