CURLOPT_PROTOCOLS(3)					     curl_easy_setopt options					      CURLOPT_PROTOCOLS(3)

NAME
       CURLOPT_PROTOCOLS - set allowed protocols

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROTOCOLS, long bitmask);

DESCRIPTION
       Pass  a long that holds a bitmask of CURLPROTO_* defines. If used, this bitmask limits what protocols libcurl may use in the transfer. This
       allows you to have a libcurl built to support a wide range of protocols but still limit specific transfers to only be allowed to use a sub-
       set of them. By default libcurl will accept all protocols it supports (CURLPROTO_ALL). See also CURLOPT_REDIR_PROTOCOLS(3).

       These are the available protocol defines:
       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

DEFAULT
       All protocols built-in

PROTOCOLS
       All

EXAMPLE
       curl = curl_easy_init();
       if(curl) {
	 /* pass in the URL from an external source */
	 curl_easy_setopt(curl, CURLOPT_URL, argv[1]);

	 /* only allow HTTP, TFTP and SFTP */
	 curl_easy_setopt(curl, CURLOPT_PROTOCOLS,
			  CURLPROTO_HTTP | CURLPROTO_TFTP | CURLPROTO_SFTP);

	 /* Perform the request */
	 curl_easy_perform(curl);
       }

AVAILABILITY
       Added in 7.19.4

RETURN VALUE
       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
