TBLT_RETC TBLT_ENTRY BltIx4GetLast(TBLT_KH *khPtr, VOID *keyBufferPtr, ULONG *recNoPtr, VOID *recordPtr); khPtr I:index file control structure keyBufferPtr O:the last key recNoPtr O:recNo of record data of last key recordPtr O:record data of last keyThis routine gets the last key and its recNo and its data record.
If the TBLT_DH.flags bit FLAGS_SKIP_DELETED_BIT
, of
khPtr->xbLinkPtr->flags, is set, this routine skips over all data
records marked with a *
(star) in the delete tag field
(the first byte of the data record).
Return: Non-zero indicates an error, otherwise the
last key/recNo/recordPtr is returned.
