SQLITE3_ENABLE_LOAD_EXTENSION(3) FreeBSD Library Functions Manual
NAME
sqlite3_enable_load_extension - Enable Or Disable Extension Loading
SYNOPSIS
int
sqlite3_enable_load_extension(sqlite3 *db, int onoff);
DESCRIPTION
So as not to open security holes in older applications that are
unprepared to deal with extension loading, and as a means of disabling
extension loading while evaluating user-entered SQL, the following API is
provided to turn the sqlite3_load_extension() mechanism on and off.
Extension loading is off by default. Call the
sqlite3_enable_load_extension() routine with onoff==1 to turn extension
loading on and call it with onoff==0 to turn it back off again.
This interface enables or disables both the C-API
sqlite3_load_extension() and the SQL function load_extension(). Use
sqlite3_db_config(db,SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION,..) to enable
or disable only the C-API.
Security warning: It is recommended that extension loading be disabled
using the SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION method rather than this
interface, so the load_extension() SQL function remains disabled. This
will prevent SQL injections from giving attackers access to extension
loading capabilities.
