#include <db_cxx.h> int DbEnv::log_stat_print(u_int32_t flags);
         The DbEnv::log_stat_print() method displays the logging subsystem
         statistical information, as described for the DbEnv::log_stat()
         method. The information is printed to a specified output channel (see
         the DbEnv::set_msgfile() 
         method for more information), or passed to an application callback
         function (see the DbEnv::set_msgcall() 
         method for more information).
    
         The DbEnv::log_stat_print() method may not be called before the
         DbEnv::open()  method is
         called.
    
         The DbEnv::log_stat_print() 
            
            
                method either returns a non-zero error value or throws an
                exception that encapsulates a non-zero error value on
                failure, and returns 0 on success.
