25 CURLOPT_PROTOCOLS \- set allowed protocols
27 #include <curl/curl.h>
29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROTOCOLS, long bitmask);
31 Pass a long that holds a bitmask of CURLPROTO_* defines. If used, this bitmask
32 limits what protocols libcurl may use in the transfer. This allows you to have
33 a libcurl built to support a wide range of protocols but still limit specific
34 transfers to only be allowed to use a subset of them. By default libcurl will
35 accept all protocols it supports (\fICURLPROTO_ALL\fP). See also
36 \fICURLOPT_REDIR_PROTOCOLS(3)\fP.
38 These are the available protocol defines:
69 All protocols built-in
74 curl = curl_easy_init();
76 /* pass in the URL from an external source */
77 curl_easy_setopt(curl, CURLOPT_URL, argv[1]);
79 /* only allow HTTP, TFTP and SFTP */
80 curl_easy_setopt(curl, CURLOPT_PROTOCOLS,
81 CURLPROTO_HTTP | CURLPROTO_TFTP | CURLPROTO_SFTP);
83 /* Perform the request */
84 curl_easy_perform(curl);
90 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
