+# 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 these 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

+# %PROTOCOLS%
+
+# 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) {
+      long protocol;
+      curl_easy_getinfo(curl, CURLINFO_PROTOCOL, &protocol);
+    }
+    curl_easy_cleanup(curl);
+  }
+}
+~~~
+
+# DEPRECATED
+
+Deprecated since 7.85.0.
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_getinfo(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
