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