## DbEnv::memp_stat_print()

    #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.
