CURLOPT_PROTOCOLS(3) Library Functions Manual CURLOPT_PROTOCOLS(3) NAME CURLOPT_PROTOCOLS - allowed protocols SYNOPSIS #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROTOCOLS, long bitmask); DESCRIPTION This option is deprecated. We strongly recommend using CURLOPT_PROTO- COLS_STR(3) instead because this option cannot control all available protocols. Pass a long that holds a bitmask of protocol bits. If used, this bit- mask 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 accepts all protocols it supports (CURL- PROTO_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 This functionality affects all supported protocols EXAMPLE int main(int argc, char **argv) { CURL *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, (long)CURLPROTO_HTTP | CURLPROTO_TFTP | CURLPROTO_SFTP); /* Perform the request */ curl_easy_perform(curl); } } DEPRECATED Deprecated since 7.85.0. AVAILABILITY Added in curl 7.19.4 RETURN VALUE curl_easy_setopt(3) returns a CURLcode indicating success or error. CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
