#include <db.h>

int DB->set_priority(DB *db, DB_CACHE_PRIORITY priority);

int DB->get_priority(DB *db, DB_CACHE_PRIORITY *priorityp);


Description: DB->set_priority

Set the cache priority for pages referenced by the DB handle.

The priority of a page biases the replacement algorithm to be more or less likely to discard a page when space is needed in the buffer pool. The bias is temporary, and pages will eventually be discarded if they are not referenced again. The DB->set_priority method is only advisory, and does not guarantee pages will be treated in a specific way.

The DB->set_priority method may be called at any time during the life of the application.

The DB->set_priority method returns a non-zero error value on failure and 0 on success.

Parameters
priority

Description: DB->get_priority

The DB->get_priority method returns the cache priority for pages referenced by the DB handle.

The DB->get_priority method may be called at any time during the life of the application.

The DB->get_priority method returns a non-zero error value on failure and 0 on success.

Parameters
priorityp
