NAME
       curl_easy_reset - reset all options of a libcurl session handle

SYNOPSIS
       #include <curl/curl.h>

       void curl_easy_reset(CURL *handle);

DESCRIPTION
       Re-initializes all options previously set on a specified CURL handle to

       It  does  not change the following information kept in the handle: live
       connections, the Session ID cache,  the  DNS  cache,  the  cookies  and
       shares.

AVAILABILITY

       Nothing
