CURLINFO_SCHEME(3) curl_easy_getinfo options 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-ter- minated string holding the URL scheme used for the most recent connec- tion 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 cor- responding CURL handle. PROTOCOLS All 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); } AVAILABILITY Added in 7.52.0 RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
