The SQLITE_CONFIG_LOG option is used to configure the SQLite global error log. (The SQLITE_CONFIG_LOG option takes two arguments: a pointer to a function with a call signature of void()(void,int,const char*), and a pointer to void. If the function pointer is not NULL, it is invoked by sqlite3_log() to process each logging event.
