+.Sh NAME
+.Nm sqlite3_load_extension
+.Nd load an extension
+.Sh SYNOPSIS
+.In sqlite3.h
+.Ft int
+.Fo sqlite3_load_extension
+.Fa "sqlite3 *db"
+.Fa "const char *zFile"
+.Fa "const char *zProc"
+.Fa "char **pzErrMsg"

+.Sh DESCRIPTION
+This interface loads an SQLite extension library from the named file.
+.Pp
+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.
+.Pp
+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
+.Fn sqlite3_load_extension
+interface shall attempt to fill *pzErrMsg with error message text stored
+in memory obtained from
+.Fn sqlite3_malloc .
+The calling function should free this memory by calling
+.Fn sqlite3_free .
+Extension loading must be enabled using
+.Fn 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.
+.Pp
+\fBSecurity warning:\fP It is recommended that the SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION
+method be used to enable only this interface.
+The use of the
+.Fn sqlite3_enable_load_extension
+interface should be avoided.
+This will keep the SQL function
+.Fn load_extension
+disabled and prevent SQL injections from giving attackers access to
+extension loading capabilities.
+.Pp
+See also the load_extension() SQL function.
+.Sh IMPLEMENTATION NOTES
+These declarations were extracted from the
+interface documentation at line 7129.
