We strongly recommend using 31CURLOPT_PROTOCOLS_STR(3) instead because this option cannot control all 32available protocols! 33 34Pass a long that holds a bitmask of CURLPROTO_* defines. If used, this bitmask 35limits what protocols libcurl may use in the transfer. This allows you to have 36a libcurl built to support a wide range of protocols but still limit specific 37transfers to only be allowed to use a subset of them. By default libcurl 38accepts all protocols it supports (*CURLPROTO_ALL*). See also 39CURLOPT_REDIR_PROTOCOLS(3). 40 41These are the available protocol defines: 42~~~c 43CURLPROTO_DICT 44CURLPROTO_FILE 45CURLPROTO_FTP 46CURLPROTO_FTPS 47CURLPROTO_GOPHER 48CURLPROTO_HTTP 49CURLPROTO_HTTPS 50CURLPROTO_IMAP 51CURLPROTO_IMAPS 52CURLPROTO_LDAP 53CURLPROTO_LDAPS 54CURLPROTO_POP3 55CURLPROTO_POP3S 56CURLPROTO_RTMP 57CURLPROTO_RTMPE 58CURLPROTO_RTMPS 59CURLPROTO_RTMPT 60CURLPROTO_RTMPTE 61CURLPROTO_RTMPTS 62CURLPROTO_RTSP 63CURLPROTO_SCP 64CURLPROTO_SFTP 65CURLPROTO_SMB 66CURLPROTO_SMBS 67CURLPROTO_SMTP 68CURLPROTO_SMTPS 69CURLPROTO_TELNET 70CURLPROTO_TFTP 71~~~ 72 73# DEFAULT 74 75All protocols built-in. 76 77# %PROTOCOLS% 78 79# EXAMPLE 80 81~~~c 82int main(int argc, char **argv) 83{ 84 CURL *curl = curl_easy_init(); 85 if(curl) { 86 /* pass in the URL from an external source */ 87 curl_easy_setopt(curl, CURLOPT_URL, argv[1]); 88 89 /* only allow HTTP, TFTP and SFTP */ 90 curl_easy_setopt(curl, CURLOPT_PROTOCOLS, 91 CURLPROTO_HTTP | CURLPROTO_TFTP | CURLPROTO_SFTP); 92 93 /* Perform the request */ 94 curl_easy_perform(curl); 95 } 96} 97~~~ 98 99# DEPRECATED 100 101Deprecated since 7.85.0. 102 103# %AVAILABILITY% 104 105# RETURN VALUE 106 107Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. 108
