Cancel Automatic Extension Loading

int sqlite3_cancel_auto_extension(void(*xEntryPoint)(void));

The sqlite3_cancel_auto_extension(X) interface unregisters the initialization routine X that was registered using a prior call to sqlite3_auto_extension(X). The sqlite3_cancel_auto_extension(X) routine returns 1 if initialization routine X was successfully unregistered and it returns 0 if X was not on the list of initialization routines.

 SQLite is in the Public Domain.

Sqlite

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
