.TH CURLOPT_DEFAULT_PROTOCOL 3 "18 Aug 2015" "libcurl 7.45.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_DEFAULT_PROTOCOL \- default protocol to use if the URL is missing a
scheme name
.SH SYNOPSIS
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DEFAULT_PROTOCOL, char
*protocol);
.SH DESCRIPTION
This option tells libcurl to use \fIprotocol\fP 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
\fICURLE_UNSUPPORTED_PROTOCOL\fP when libcurl parses a schemeless URL. Parsing
happens when \fIcurl_easy_perform(3)\fP or \fIcurl_multi_perform(3)\fP is
called. The protocols supported by libcurl will vary depending on how it was
built. Use \fIcurl_version_info(3)\fP 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
\fICURLOPT_URL(3)\fP for details.
.SH DEFAULT
NULL (make a guess based on the host)
.SH PROTOCOLS
All
.SH EXAMPLE
.nf
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);
}
.fi
.SH AVAILABILITY
Added in 7.45.0
.SH RETURN VALUE
CURLE_OK if the option is supported.

CURLE_OUT_OF_MEMORY if there was insufficient heap space.

CURLE_UNKNOWN_OPTION if the option is not supported.
