CURLINFO_PROTOCOL(3) libcurl CURLINFO_PROTOCOL(3)
NAME
CURLINFO_PROTOCOL - get the protocol used in the connection
SYNOPSIS
#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 pos-
sible 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:
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
All
EXAMPLE
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);
}
