Like when we list a series of options and then want to add "normal" text again afterwards. Without this, the indentation level wrongly continues even after the final "##" header, making following text wrongly appear to belong to the header above. Adjusted several curldown files to use this. Fixes #13803 Reported-by: Jay Satiro Closes #13806

NAME
CURLOPT_PROXY_SSLVERSION - preferred HTTPS proxy TLS version
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLVERSION,
long version);
DESCRIPTION
Pass a long as parameter to control which version of SSL/TLS to attempt to use when connecting to an HTTPS proxy.
Use one of the available defines for this purpose. The available options are:
CURL_SSLVERSION_DEFAULT
The default action. This attempts to figure out the remote SSL protocol version.
CURL_SSLVERSION_TLSv1
TLSv1.x
CURL_SSLVERSION_TLSv1_0
TLSv1.0
CURL_SSLVERSION_TLSv1_1
TLSv1.1
CURL_SSLVERSION_TLSv1_2
TLSv1.2
CURL_SSLVERSION_TLSv1_3
TLSv1.3
The maximum TLS version can be set by using one of the CURL_SSLVERSION_MAX_ macros below. It is also possible to OR one of the CURL_SSLVERSION_ macros with one of the CURL_SSLVERSION_MAX_ macros. The MAX macros are not supported for WolfSSL.
CURL_SSLVERSION_MAX_DEFAULT
The flag defines the maximum supported TLS version as TLSv1.2, or the default value from the SSL library. (Added in 7.54.0)
CURL_SSLVERSION_MAX_TLSv1_0
The flag defines maximum supported TLS version as TLSv1.0. (Added in 7.54.0)
CURL_SSLVERSION_MAX_TLSv1_1
The flag defines maximum supported TLS version as TLSv1.1. (Added in 7.54.0)
CURL_SSLVERSION_MAX_TLSv1_2
The flag defines maximum supported TLS version as TLSv1.2. (Added in 7.54.0)
CURL_SSLVERSION_MAX_TLSv1_3
The flag defines maximum supported TLS version as TLSv1.3. (Added in 7.54.0)
In versions of curl prior to 7.54 the CURL_SSLVERSION_TLS options were documented to allow only the specified TLS version, but behavior was inconsistent depending on the TLS library.
DEFAULT
CURL_SSLVERSION_DEFAULT
EXAMPLE
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* ask libcurl to use TLS version 1.0 or later */
curl_easy_setopt(curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1);
/* Perform the request */
curl_easy_perform(curl);
}
}
AVAILABILITY
Added in 7.52.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
