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 deleteThis 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.
