Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

# NAME
|
|
|
|
CURLINFO_SCHEME - get the URL scheme (sometimes called protocol) used in the connection
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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.
|
|
|
|
# EXAMPLE
|
|
|

~~~c
|
|
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 */
|
|
}
