#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTPPOST, struct curl_httppost *formpost);
Using POST with HTTP 1.1 implies the use of a "Expect: 100-continue" header. You can disable this header with CURLOPT_HTTPHEADER(3).
When setting CURLOPT_HTTPPOST(3), it will automatically set CURLOPT_NOBODY(3) to 0.
This option is deprecated! Do not use it. Use CURLOPT_MIMEPOST(3) instead after having prepared mime data.
