+=head1 NAME
+
+SSL_CTX_set_min_proto_version, SSL_CTX_set_max_proto_version,
+SSL_set_min_proto_version, SSL_set_max_proto_version - Set minimum
+and maximum supported protocol version
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ int SSL_CTX_set_min_proto_version(SSL_CTX *ctx, int version);
+ int SSL_CTX_set_max_proto_version(SSL_CTX *ctx, int version);
+ int SSL_set_min_proto_version(SSL *ssl, int version);
+ int SSL_set_max_proto_version(SSL *ssl, int version);
+
+=head1 DESCRIPTION
+
+The functions set the minimum and maximum supported protocol versions
+for the B<ctx> or B<ssl>.
+This works in combination with the options set via
+L<SSL_CTX_set_options(3)> that also make it possible to disable
+specific protocol versions.
+Use these functions instead of disabling specific protocol versions.
+
+Setting the minimum or maximum version to 0, will enable protocol
+versions down to the lowest version, or up to the highest version
+supported by the library, respectively.
+
+Currently supported versions are B<SSL3_VERSION>, B<TLS1_VERSION>,
+B<TLS1_1_VERSION>, B<TLS1_2_VERSION> for TLS and B<DTLS1_VERSION>,
+B<DTLS1_2_VERSION> for DTLS.
+
+=head1 RETURN VALUES
+
+These functions return 1 on success and 0 on failure.
+
+=head1 NOTES
+
+All these functions are implemented using macros.
+
+=head1 HISTORY
+
+The functions were added in OpenSSL 1.1.0
