TBLT_RETC TBLT_ENTRY BltIx4GetFirst(TBLT_KH *khPtr,
VOID *keyBufferPtr,
ULONG *recNoPtr,
VOID *recordPtr);
khPtr I:index file control structure
keyBufferPtr O:the first key
recNoPtr O:recNo of record data of first key
recordPtr O:record data of first key
This routine gets the first 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
first key/recNo/recordPtr is returned.
