Use one of these protocol (scheme) names: dict, file, ftp, ftps, gopher, http, https, imap, imaps, ldap, ldaps, pop3, pop3s, rtsp, scp, sftp, smb, smbs, smtp, smtps, telnet, tftp An unknown or unsupported protocol causes error \fICURLE_UNSUPPORTED_PROTOCOL\fP when libcurl parses a schemeless URL. Parsing happens when \fIcurl_easy_perform(3)\fP or \fIcurl_multi_perform(3)\fP is called. The protocols supported by libcurl will vary depending on how it was built. Use \fIcurl_version_info(3)\fP if you need a list of protocol names supported by the build of libcurl that you are using. This option does not change the default proxy protocol (http). Without this option libcurl would make a guess based on the host, see \fICURLOPT_URL(3)\fP for details. .SH DEFAULT NULL (make a guess based on the host) .SH PROTOCOLS All .SH EXAMPLE .nf curl = curl_easy_init(); if(curl) { /* set a URL without a scheme */ curl_easy_setopt(curl, CURLOPT_URL, "example.com"); /* set the default protocol (scheme) for schemeless URLs */ curl_easy_setopt(curl, CURLOPT_DEFAULT_PROTOCOL, "https"); /* Perform the request */ curl_easy_perform(curl); } .fi .SH AVAILABILITY Added in 7.45.0 .SH RETURN VALUE CURLE_OK if the option is supported. CURLE_OUT_OF_MEMORY if there was insufficient heap space. CURLE_UNKNOWN_OPTION if the option is not supported. .SH "SEE ALSO" .BR CURLOPT_URL "(3), "
