###

    #include <db.h>

    int
    DBENV->set_mutexlocks(DB_ENV *dbenv, int do_lock);

# Description

Toggle mutex locks. Setting do_lock to a zero value causes Berkeley DB to grant all requested mutual exclusion mutexes without testing for their availability.

The DBENV->set_mutexlocks interface affects the entire application, not only the environment in which it is called.

This functionality should never be used for any other purpose than debugging.

The DBENV->set_mutexlocks interface may be used to configure Berkeley DB at any time during the life of the application.

The DBENV->set_mutexlocks function returns a non-zero error value on failure and 0 on success.

# Errors

EINVAL
  An invalid flag value or parameter was specified.
