CURLOPT_DEFAULT_PROTOCOL(3) libcurl CURLOPT_DEFAULT_PROTOCOL(3)
NAME
CURLOPT_DEFAULT_PROTOCOL - default protocol to use if the URL is miss-
ing a scheme name
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DEFAULT_PROTOCOL,
char *protocol);
DESCRIPTION
This option tells libcurl to use protocol if the URL is missing a
scheme name.
Use one of these protocol (scheme) names:
dict, file, ftp, ftps, gopher, http, https, imap, imaps, ldap, ldaps,
pop3, pop3s, rtsp, scp, sftp, smb, smbs, smtp, smtps, telnet, tftp
An unknown or unsupported protocol causes error CURLE_UNSUPPORTED_PRO-
TOCOL when libcurl parses a URL without a scheme. Parsing happens when
curl_easy_perform(3) or curl_multi_perform(3) is called. The protocol
set supported by libcurl vary depending on how it was built. Use
curl_version_info(3) if you need a list of protocol names supported by
the build of libcurl that you are using.
This option does not change the default proxy protocol (http).
Without this option libcurl would make a guess based on the host, see
CURLOPT_URL(3) for details.
The application does not have to keep the string around after setting
this option.
DEFAULT
NULL (make a guess based on the host)
PROTOCOLS
All
EXAMPLE
curl = curl_easy_init();
if(curl) {
/* set a URL without a scheme */
curl_easy_setopt(curl, CURLOPT_URL, "example.com");
/* set the default protocol (scheme) for schemeless URLs */
curl_easy_setopt(curl, CURLOPT_DEFAULT_PROTOCOL, "https");
/* Perform the request */
curl_easy_perform(curl);
}
AVAILABILITY
Added in 7.45.0
