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
