This interface loads an SQLite extension library from the named file. Extension loading must be enabled using sqlite3_enable_load_extension() or sqlite3_db_config(db,SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION,1,NULL) prior to calling this API, otherwise an error will be returned. This will prevent SQL injections from giving attackers SQLite has the ability to load extensions (including newapplication-defined SQL functions,collating sequences, virtual tables, and VFSes) at run-time.This feature allows the code for extensions to be developed andtested separately from the application and then loadedon an as-needed basis. feature = "load_extension" Disable loading of SQLite extensions. feature = "load_extension" Disable loading of SQLite extensions. sqlite3_enable_load_extension() or Reliable.
