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 bit-
       mask);


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 subset
       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.
