SSL_CTX_use_serverinfo, SSL_CTX_use_serverinfo_file - use serverinfo extension
=head1 SYNOPSIS
#include <openssl/ssl.h>
int SSL_CTX_use_serverinfo(SSL_CTX *ctx, const unsigned char *serverinfo,
size_t serverinfo_length);
int SSL_CTX_use_serverinfo_file(SSL_CTX *ctx, const char *file);
=head1 DESCRIPTION
These functions load "serverinfo" TLS ServerHello Extensions into the SSL_CTX.
A "serverinfo" extension is returned in response to an empty ClientHello
Extension.
SSL_CTX_use_serverinfo() loads one or more serverinfo extensions from
a byte array into B<ctx>. The extensions must be concatenated into a
sequence of bytes. Each extension must consist of a 2-byte Extension Type,
a 2-byte length, and then length bytes of extension_data.
SSL_CTX_use_serverinfo_file() loads one or more serverinfo extensions from
B<file> into B<ctx>. The extensions must be in PEM format. Each extension
must consist of a 2-byte Extension Type, a 2-byte length, and then length
bytes of extension_data. Each PEM extension name must begin with the phrase
"BEGIN SERVERINFO FOR ".
