The server uses 'current_thd' in such a case.
It should probably be in the plugin.h, I'd say. But at the moment it is

extern pthread_key_t THR_THD;
THD *current_thd() { return (THD*)pthread_getspecific(THR_THD); }

if you want it to work on windows, see mysql_priv.h for the complete
definition of current_thd.
