#include <db_cxx.h>

int
DbMpoolFile::get_priority(DB_CACHE_PRIORITY *priorityp);

The DbMpoolFile::get_priority() method may be called at any time during the life of the application.

The DbMpoolFile::get_priority() 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.
