SQLITE_SYNC_NORMAL(3)      Library Functions Manual      SQLITE_SYNC_NORMAL(3)

NAME
     SQLITE_SYNC_NORMAL, SQLITE_SYNC_FULL, SQLITE_SYNC_DATAONLY -
     Synchronization Type Flags

SYNOPSIS
     #define SQLITE_SYNC_NORMAL
     #define SQLITE_SYNC_FULL
     #define SQLITE_SYNC_DATAONLY

DESCRIPTION
     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.)
