Description

The DbEnv::memp_register method registers page-in and page-out functions for files of type ftype in the specified pool.

If the pgin_fcn function is non-NULL, it is called each time a page is read into the memory pool from a file of type ftype, or a page is created for a file of type ftype (see the DB_MPOOL_CREATE flag for the DbMpoolFile::get method).

If the pgout_fcn function is non-NULL, it is called each ...
