     18 CURLINFO_PROTOCOL - get the protocol used in the connection

     20 # SYNOPSIS
     21 
     22 ~~~c
     23 #include <curl/curl.h>
     24 
     25 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PROTOCOL, long *p);

     28 # DESCRIPTION
     29 
     30 This option is deprecated. We strongly recommend using
     31 CURLINFO_SCHEME(3) instead, because this option cannot return all
     32 possible protocols.
     33 
     34 Pass a pointer to a long to receive the version used in the last http
     35 connection. The returned value is set to one of these values:
     36 
     37 ~~~c
     38 CURLPROTO_DICT, CURLPROTO_FILE, CURLPROTO_FTP, CURLPROTO_FTPS,
     39 CURLPROTO_GOPHER, CURLPROTO_HTTP, CURLPROTO_HTTPS, CURLPROTO_IMAP,
     40 CURLPROTO_IMAPS, CURLPROTO_LDAP, CURLPROTO_LDAPS, CURLPROTO_POP3,
     41 CURLPROTO_POP3S, CURLPROTO_RTMP, CURLPROTO_RTMPE, CURLPROTO_RTMPS,
     42 CURLPROTO_RTMPT, CURLPROTO_RTMPTE, CURLPROTO_RTMPTS, CURLPROTO_RTSP,
     43 CURLPROTO_SCP, CURLPROTO_SFTP, CURLPROTO_SMB, CURLPROTO_SMBS, CURLPROTO_SMTP,
     44 CURLPROTO_SMTPS, CURLPROTO_TELNET, CURLPROTO_TFTP, CURLPROTO_MQTT
