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

RETURN VALUE
Returns CURLE_OK if HTTP is supported, and CURLE_UNKNOWN_OPTION if not.
