How to get protocol, characterset, mysql info?

Hi,

I know the API to get protocol version, character set etc. If I want to find out the current protocol version, current user character set, mysql info, mysql server info wihtout using these API -
mysql_get_server_info()
mysql_info()
mysql_get_proto_info()
mysql_character_set_name()
mysql_get_client_info().

Is there any other way to get these information without using API?

I don't want to use API instead Shall I get these information from Infomrmation_schema?

Can I fetch these information directly accessing enviornment variable if possible?

I find out the value of protocol, version, character set, host name using

select @@hostname
select @@version
select @@protocol_version
select @@character_server_set.

But couldn't find out the how to get values of

mysql_get_client_info()
mysql_info()
mysql_stat()
mysql_thread_safe()
without using it in the same manner used for protocol,character set etc.
