.TH CURLOPT_PROTOCOLS 3 "August 22, 2023" "ibcurl 8.3.0" libcurl
.SH NAME
CURLOPT_PROTOCOLS \- allowed protocols
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROTOCOLS, long bitmask);
.fi
.SH DESCRIPTION
This option is deprecated. We strongly recommend using
\fICURLOPT_PROTOCOLS_STR(3)\fP 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 (\fICURLPROTO_ALL\fP). See also
\fICURLOPT_REDIR_PROTOCOLS(3)\fP.
These are the available protocol defines:
.nf
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
.fi
.SH DEFAULT
All protocols built-in.
.SH PROTOCOLS
All
.SH EXAMPLE
.nf
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);
}
.fi
.SH AVAILABILITY
Added in 7.19.4. Deprecated since 7.85.0.
.SH RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
.SH "SEE ALSO"
