## SQLite C Interface

## Synchronization Type Flags

>     #define SQLITE_SYNC_NORMAL        0x00002
>     #define SQLITE_SYNC_FULL          0x00003
>     #define SQLITE_SYNC_DATAONLY      0x00010

When SQLite invokes the xSync() method of an sqlite3_io_methods object it uses a combination of these integer values as the second argument.

When the SQLITE_SYNC_DATAONLY flag is used, it means that the sync operation only needs to flush data to mass storage. Inode information need not be flushed. If the lower four bits of the flag equal SQLITE_SYNC_NORMAL, that means to use normal fsync() semantics. If the lower four bits equal SQLITE_SYNC_FULL, that means to use Mac OS X style fullsync instead of fsync().
