|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HTTP_VERSION, long version);
|
|
.SH DESCRIPTION
|
|
Pass \fIversion\fP a long, set to one of the values described below. They
|
|
force libcurl to use the specific HTTP versions. This is not sensible to do
|
|
unless you have a good reason. You have to set this option if you want to use
|
|
libcurl's HTTP/2 support.
|
|
|
|
.IP CURL_HTTP_VERSION_NONE
|
|
We don't care about what version the library uses. libcurl will use whatever
|
|
it thinks fit.
|
|
.IP CURL_HTTP_VERSION_1_0
|
|
Enforce HTTP 1.0 requests.
|
|
.IP CURL_HTTP_VERSION_1_1
|
|
Enforce HTTP 1.1 requests.
|
|
.IP CURL_HTTP_VERSION_2_0
|
|
Attempt HTTP 2.0 requests. libcurl will fall back to HTTP 1.x if HTTP 2.0
|
|
can't be negotiated with the server.
|
|

|
|
CURL_HTTP_VERSION_NONE
