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);
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 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 file into 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 ".
NOTESRETURN VALUES
On success, the functions return 1. On failure, the functions return
0. Check out the error stack to find out the reason.
