NAME

       CURLINFO_SCHEME - get the URL scheme (sometimes called protocol) used in the connection

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SCHEME, char **scheme);

DESCRIPTION

       Pass  a  pointer  to  a  char  pointer  to receive the pointer to a null-terminated string
       holding the URL scheme used for the most recent connection done with this CURL handle.

       The scheme pointer will be NULL or pointing to private memory you MUST NOT free - it  gets
       freed when you call curl_easy_cleanup(3) on the corresponding CURL handle.

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         CURLcode res;
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
         res = curl_easy_perform(curl);
         if(res == CURLE_OK) {
           char *scheme = NULL;
           curl_easy_getinfo(curl, CURLINFO_SCHEME, &scheme);
           if(scheme)
             printf("scheme: %s\n", scheme); /* scheme: HTTP */
         }
         curl_easy_cleanup(curl);
