Note: Due to the non-exclusive nature of Unix, this funcation can be successfully executed on a file that was opened by several other applications in shared mode. However, although the function succeeds, it may cause havoc for the other applications. This can be pre- vented by enforcing exclusivity with locks, but this is not the default mode.

Returns

ctdbAlterTable returns CTDBRET_OK if successful, or the c-tree Plus error code on failure.
