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.

PROTOCOLS

EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
  CURLcode res;
  curl_easy_setopt(curl, CURLOPT_URL, "http://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);
}
