NAME
       CURLOPT_PROXY_SSLVERSION - set preferred proxy TLS/SSL 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 will attempt 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

	      CURL_SSLVERSION_MAX_DEFAULT
		     The  flag	defines  maximum  supported  TLS  version as TLSv1.2 or default value from SSL library. Only library NSS currently
		     allows to get maximum supported TLS version.  (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)
