PL_HashTableRemove
==================

Removes the entry with the specified key from the hash table.


Syntax
------

.. code::

   #include <plhash.h>

   PRBool PL_HashTableRemove(
     PLHashTable *ht,
     const void *key);


Parameters
~~~~~~~~~~

The function has the following parameters:

``ht``
   A pointer to the hash table from which to remove the entry.
``key``
   A pointer to the key for the entry to be removed.


Description
-----------

If there is no entry in the table with the specified key,
:ref:`PL_HashTableRemove` returns ``PR_FALSE``. If the entry exists,
:ref:`PL_HashTableRemove` removes the entry from the table, invokes
``freeEntry`` with the ``HT_FREE_ENTRY`` flag to frees the entry, and
returns ``PR_TRUE``.

If the table is underloaded, :ref:`PL_HashTableRemove` also shrinks the
number of buckets by half.


Remark
------

This function should return :ref:`PRStatus`.
