CURLINFO_SCHEME(3) Introduction to Library Functions 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 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.

The returned scheme might be upper or lowercase. Do comparisons case
insensitively.

PROTOCOLS

This functionality affects all supported protocols

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 */
}
curl_easy_cleanup(curl);
}
}

AVAILABILITY
