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().

+ +

Do not confuse the SQLITE_SYNC_NORMAL and SQLITE_SYNC_FULL flags +with the PRAGMA synchronous=NORMAL and PRAGMA synchronous=FULL +settings. The synchronous pragma determines when calls to the +xSync VFS method occur and applies uniformly across all platforms. +The SQLITE_SYNC_NORMAL and SQLITE_SYNC_FULL flags determine how +energetic or rigorous or forceful the sync operations are and +only make a difference on Mac OSX for the default SQLite code. +(Third-party VFS implementations might also make the distinction +between SQLITE_SYNC_NORMAL and SQLITE_SYNC_FULL, but among the +operating systems natively supported by SQLite, only Mac OSX +cares about the difference.) +
