TBLT_RETC TBLT_ENTRY BltIx4GetNext(TBLT_KH *khPtr, VOID *keyBufferPtr, ULONG *recNoPtr, VOID *recordPtr); khPtr I:index file control structure keyBufferPtr IO:the next key recNoPtr IO:recNo of record data of the next key recordPtr O:record data of next keyThis routine gets the next 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).
This routine will use the contents of keyBufferPtr and recNoPtr as a
starting point if FLAGS_ATOMIC_BIT
was used as the mode
when the index file was opened.
Return: Non-zero indicates an error, otherwise the
next key/recNo/recordPtr is returned.
