When a +programmer associates a mutex with an arbitrary collection of data, the +mutex provides a protective monitor around the data. + +In general, a monitor is a conceptual entity composed of a mutex, one or +more condition variables, and the monitored data. Monitors in this +generic sense should not be confused with monitors used in Java +programming. In addition to :ref:`PRLock`, NSPR provides another mutex +type, :ref:`PRMonitor`, which is reentrant and can have only one associated +condition variable. :ref:`PRMonitor` is intended for use with Java and +reflects the Java approach to thread synchronization. + +For an introduction to NSPR thread synchronization, including locks and +condition variables, see `Introduction to +NSPR <Introduction_to_NSPR>`__. + +For reference information on NSPR condition variables, see `Condition +Variables <Condition_Variables>`__. + +.. _Lock_Type: + +Lock Type +--------- + + - :ref:`PRLock` + +.. _Lock_Functions: + +Lock Functions +-------------- + + - :ref:`PR_NewLock` creates a new lock object. + - :ref:`PR_DestroyLock` destroys a specified lock object. + - :ref:`PR_Lock` locks a specified lock object. + - :ref:`PR_Unlock` unlocks a specified lock object. |
