CURLOPT_DEFAULT_PROTOCOL(3)                           curl_easy_setopt options

NAME

CURLOPT_DEFAULT_PROTOCOL - default protocol to use if the URL is missing 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_PROTOCOL when libcurl parses a schemeless URL. Parsing happens when curl_easy_perform(3) or curl_multi_perform(3) is called. The protocols supported by libcurl will 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

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.
