.TH CURLOPT_DEFAULT_PROTOCOL 3 "August 22, 2023" "ibcurl 8.3.0" libcurl
|
||
|
|
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_DEFAULT_PROTOCOL \- default protocol to use if the URL is missing a
|
||
|
|
scheme name
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DEFAULT_PROTOCOL,
|
||
|
|
char *protocol);
|
||
|
|
.fi
|
||
|
|
.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 URL without a
|
||
|
|
scheme. Parsing happens when \fIcurl_easy_perform(3)\fP or
|
||
|
|
\fIcurl_multi_perform(3)\fP is called. The protocol set supported by libcurl
|
||
|
|
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.
|
||
|
|
|
||
|
|
The application does not have to keep the string around after setting this
|
||
|
|
option.
|
||
|
|
.SH DEFAULT
|
||
|
|
NULL (make a guess based on the host)
