#include <db_cxx.h> int DbEnv::memp_stat_print(u_int32_t flags);
         The DbEnv::memp_stat_print() method displays cache
         subsystem statistical information, as described for the 
         DbEnv::memp_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::memp_stat_print() method may not be called before the
         DbEnv::open()  method is
         called.
    
         The DbEnv::memp_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.
