CURLOPT_PROTOCOLS(3) libcurl 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 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 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
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. Deprecated since 7.85.0.
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
