SQLITE3_LOAD_EXTENSION(3) FreeBSD Library Functions Manual NAME sqlite3_load_extension - Load An Extension SYNOPSIS int sqlite3_load_extension(sqlite3 *db, const char *zFile, const char *zProc, char **pzErrMsg ); DESCRIPTION This interface loads an SQLite extension library from the named file. The sqlite3_load_extension() interface attempts to load an SQLite extension library contained in the file zFile. If the file cannot be loaded directly, attempts are made to load with various operating-system specific extensions added. So for example, if "samplelib" cannot be loaded, then names like "samplelib.so" or "samplelib.dylib" or "samplelib.dll" might be tried also. The entry point is zProc. zProc may be 0, in which case SQLite will try to come up with an entry point name on its own. It first tries "sqlite3_extension_init". If that does not work, it constructs a name "sqlite3_X_init" where the X is consists of the lower-case equivalent of all ASCII alphabetic characters in the filename from the last "/" to the first following "." and omitting any initial "lib". The sqlite3_load_extension() interface returns SQLITE_OK on success and SQLITE_ERROR if something goes wrong. If an error occurs and pzErrMsg is not 0, then the sqlite3_load_extension() interface shall attempt to fill *pzErrMsg with error message text stored in memory obtained from sqlite3_malloc(). The calling function should free this memory by calling sqlite3_free(). 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. Security warning: It is recommended that the SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION method be used to enable only this interface. The use of the sqlite3_enable_load_extension() interface should be avoided. This will keep the SQL function load_extension() disabled and prevent SQL injections from giving attackers access to extension loading capabilities. See also the load_extension() SQL function.
