TBLT_RETC TBLT_ENTRY BltIx4DeleteKey(TBLT_KH *khPtr,
                                     VOID *keyBufferPtr,
                                     ULONG recNo);


 khPtr          I:index file control structure
 keyBufferPtr   I:key to delete
 recNo          I:recNo that is attached to key to delete

This routine deletes the key/recNo pair.

This routine is typically used to physically remove a key that was previously stored into the index file (for transaction rollback). The recNo is the data (32-bit value) that is attached to the key and stored in the index file (typically, this is the record number of the associated data record in the DBF file).

Return:  Non-zero indicates an error, otherwise the key is deleted.
