+PL_NewHashTable
+===============
+
+Create a new hash table.
+
+
+Syntax
+------
+
+.. code::
+
+ #include <plhash.h>
+
+ PLHashTable *PL_NewHashTable(
+ PRUint32 numBuckets,
+ PLHashFunction keyHash,
+ PLHashComparator keyCompare,
+ PLHashComparator valueCompare,
+ const PLHashAllocOps *allocOps,
+ void *allocPriv
+ );
+
+
+Parameters
+~~~~~~~~~~
+
+The function has the following parameters:
+
+``numBuckets``
+ The number of buckets in the hash table.
+``keyHash``
+ Hash function.
+``keyCompare``
+ Function used to compare keys of entries.
+``valueCompare``
+ Function used to compare keys of entries.
+``allocOps``
+ A pointer to a ``PLHashAllocOps`` structure that must exist
+ throughout the lifetime of the new hash table.
+``allocPriv``
+ Passed as the first argument (pool).
+
+
+Returns
+~~~~~~~
+
+The new hash table.
+
+
+Description
+-----------
+
+:ref:`PL_NewHashTable` creates a new hash table. The table has at least 16
+buckets. You can pass a value of 0 as ``numBuckets`` to create the
+default number of buckets in the new table. The arguments ``keyCompare``
+and ``valueCompare`` are functions of type :ref:`PLHashComparator` that the
+hash table library functions use to compare the keys and the values of
+entries.
+
+The argument ``allocOps`` points to a ``PLHashAllocOps`` structure that
+must exist throughout the lifetime of the new hash table. The hash table
+library functions do not make a copy of this structure. When the
+allocation functions in ``allocOps`` are invoked, the allocation private
+data allocPriv is passed as the first argument (pool). You can specify a
+``NULL`` value for ``allocOps`` to use the default allocation functions.
+If ``allocOps`` is ``NULL``, ``allocPriv`` is ignored. Note that the
+default ``freeEntry`` function does not free the value of the entry.
