# NAME
|
|
|
|
CURLOPT_PROTOCOLS - allowed protocols
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROTOCOLS, long bitmask);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
This option is deprecated. We strongly recommend using
|
|
CURLOPT_PROTOCOLS_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 (*CURLPROTO_ALL*). See also
|
|
CURLOPT_REDIR_PROTOCOLS(3).
|
|
|
|
These are the available protocol defines:
|
|
~~~c
|
|
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
|

|
# DEFAULT

|
|
|
All protocols built-in.
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
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,
|
|
CURLPROTO_HTTP | CURLPROTO_TFTP | CURLPROTO_SFTP);
|
|
|
|
/* Perform the request */
|
|
curl_easy_perform(curl);
|
|
}
|
|
}
