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_PROTOCOL - get the protocol used in the connection
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PROTOCOL, long *p);

# DESCRIPTION
|
|
|
|
This option is deprecated. We strongly recommend using
|
|
CURLINFO_SCHEME(3) instead, because this option cannot return all
|
|
possible protocols!
|
|
|
|
Pass a pointer to a long to receive the version used in the last http
|
|
connection. The returned value is set to one of the CURLPROTO_* values:
|
|
|
|
~~~c
|
|
CURLPROTO_DICT, CURLPROTO_FILE, CURLPROTO_FTP, CURLPROTO_FTPS,
|
|
CURLPROTO_GOPHER, CURLPROTO_HTTP, CURLPROTO_HTTPS, CURLPROTO_IMAP,
|
|
CURLPROTO_IMAPS, CURLPROTO_LDAP, CURLPROTO_LDAPS, CURLPROTO_POP3,
|
|
CURLPROTO_POP3S, CURLPROTO_RTMP, CURLPROTO_RTMPE, CURLPROTO_RTMPS,
|
|
CURLPROTO_RTMPT, CURLPROTO_RTMPTE, CURLPROTO_RTMPTS, CURLPROTO_RTSP,
|
|
CURLPROTO_SCP, CURLPROTO_SFTP, CURLPROTO_SMB, CURLPROTO_SMBS, CURLPROTO_SMTP,
|
|
CURLPROTO_SMTPS, CURLPROTO_TELNET, CURLPROTO_TFTP, CURLPROTO_MQTT

if(curl) {

|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
|
|
res = curl_easy_perform(curl);
|
|
if(res == CURLE_OK) {
|
|
long protocol;
|
|
curl_easy_getinfo(curl, CURLINFO_PROTOCOL, &protocol);
|
|
}
|
