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 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.
