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 is NULL or points to private memory. You MUST NOT free - it gets freed when  you  call
       curl_easy_cleanup(3) on the corresponding CURL handle.

PROTOCOLS

       All

EXAMPLE

       int main(void)
       {
         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 */
           }
