DESCRIPTION
Convenience macros to retrieve DBHashTable structure elements.DBH_KEYLENGTH ()
This macro returns the keylenth in bytes associated to the DBHashTable. The value is fixed when the DBHashTable is created with dbh_create.DBH_RECORD_SIZE ()
This macro returns the size of the current record loaded in memory. If no record has been loaded, then the return value is not defined.DBH_KEY ()
This macro returns a pointer to the current DBHashTable key area.DBH_DATA ()
This macro returns a pointer to the current DBHashTable data area.DBH_ERASED_SPACE ()
This macro returns the amount of bytes taken up by erased data in the DBHashTable.DBH_DATA_SPACE ()
This macro returns the amount of bytes taken up by valid data in the DBHashTable.DBH_TOTAL_SPACE ()
This macro returns the total amount of bytes taken up by the DBHashTable.DBH_FORMAT_SPACE ()
This macro returns the total amount of bytes taken up by the format of the DBHashTable.DBH_RECORDS ()
This macro returns the number of records in the DBHashTable.DBH_MAXIMUM_RECORD_SIZE ()
This macro returns the maximum allocated space for data in the current DBHashTable record.DBH_PATH ()
This macro returns a pointer to a string containing the path to the current DBHashTable.SEE ALSO
