Checkpoint a database
int sqlite3_wal_checkpoint(sqlite3 *db, const char *zDb);
The sqlite3_wal_checkpoint(D,X) is equivalent to sqlite3_wal_checkpoint_v2(D,X,SQLITE_CHECKPOINT_PASSIVE,0,0).
In brief, sqlite3_wal_checkpoint(D,X) causes the content in the write-ahead log for database X on database connection D to be transferred into the database file and for the write-ahead log to be reset. See the checkpointing documentation for addition information.
This interface used to be the only way to cause a checkpoint to occur. But then the newer and more powerful sqlite3_wal_checkpoint_v2() interface was added. This interface is retained for backwards compatibility and as a convenience for applications that need to manually start a callback but which do not need the full power (and corresponding complication) of sqlite3_wal_checkpoint_v2().

SQLite,是一款轻型的数据库,是遵守ACID的关系型数据库管理系统,它包含在一个相对小的C库中。它是D.RichardHipp建立的公有领域项目。它的设计目标是嵌入式的,而且目前已经在很多嵌入式产品中使用了它,它占用资源非常的低,在嵌入式设备中,可能只需要几百K的内存就够了。它能够支持Windows/Linux/Unix等等主流的操作系统,同时能够跟很多程序语言相结合,比如 Tcl、C#、PHP、Java等,还有ODBC接口,同样比起Mysql、PostgreSQL这两款开源的世界著名数据库管理系统来
