###

    #include <db_cxx.h>

    static int
    DbEnv::set_panicstate(int do_lock);

# Description

Toggle the Berkeley DB panic state. Setting do_lock to a non-zero value causes Berkeley DB to refuse attempts to call Berkeley DB functions with the DB_RUNRECOVERY error return.

The DbEnv::set_panicstate interface affects the entire application, not a single database or database environment.

While the DbEnv::set_panicstate interface may be used to configure Berkeley DB at any time during the life of the application, it should normally be called before making any calls to the db_env_create or db_create methods.

The DbEnv::set_panicstate method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.

# Errors

EINVAL
  An invalid flag value or parameter was specified.
