TBLT_RETC TBLT_ENTRY BltIx4PrevKey(TBLT_KH *khPtr,
                                   VOID *keyBufferPtr,
                                   ULONG *recNoPtr);


 khPtr          I:index file control structure
 keyBufferPtr   IO:the previous key
 recNoPtr       IO:recNo attached to the previous key

This routine gets the previous key and its recNo.

See also: BltIx4GetPrev().

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 previous key/recNo is returned.
