dbh_regen_sweep man page


dbh_regen_sweep, dbh_regen_fanout, dbh_settempdir — make physical structure of the DBHashTable congruent with logical structure


#include <dbh.h>

DBHashTable *dbh_regen_sweep (DBHashTable *dbh);
DBHashTable *dbh_regen_fanout (DBHashTable *dbh);
int dbh_settempdir (DBHashTable *dbh, char *temp_dir);


Regenerate the DBHashTable eliminating erased records and optimizing disk access and speed for  sweep access using dbh_regen_sweep and for fanout access using dbh_regen_fanout. This is done by creating a new DBHashTable where the physical structure matches the logical structure. The temporary directory where the new DBHashTable is created may be set with  dbh_settempdir().  Current DBHashTable is closed before removed. New DBHashTable is opened after renamed.

Return Value

A pointer to the new DBHashTable.
