#include <db_cxx.h> int DbEnv::txn_stat_print(u_int32_t flags);
         The DbEnv::txn_stat_print() method displays the transaction
         subsystem statistical information, as described for the
         DbEnv::txn_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::txn_stat_print() method may not be called before the
         DbEnv::open()  method is
         called.
    
         The DbEnv::txn_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.
            
        
    
The flags parameter must be set to 0 or by bitwise inclusively OR'ing together one or more of the following values:
                  DB_STAT_ALL
            
Display all available information.
                  DB_STAT_ALLOC
            
Display allocation information. To display allocation information, both DB_STAT_ALLOC and DB_STAT_ALL need to be set.
                  DB_STAT_CLEAR
            
Reset statistics after displaying their values.
