CURLINFO_SCHEME(3)                  libcurl                 CURLINFO_SCHEME(3)


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);
       }
