CURLINFO_PROTOCOL(3) | curl_easy_getinfo options | 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 possible protocols!
Pass a pointer to a long to receive the version used in the last http connection. The returned value will be exactly 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); }
AVAILABILITY¶
Added in 7.52.0. Deprecated since 7.85.0.
RETURN VALUE¶
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
