PL_HashTableAdd
===============
Add a new entry with the specified key and value to the hash table.
Syntax
------
.. code::
#include <plhash.h>
PLHashEntry *PL_HashTableAdd(
PLHashTable *ht,
const void *key,
void *value);
Parameters
~~~~~~~~~~
The function has the following parameters:
``ht``
A pointer to the the hash table to which to add the entry.
``key``
A pointer to the key for the entry to be added.
``value``
A pointer to the value for the entry to be added.
Returns
~~~~~~~
A pointer to the new entry.
Description
-----------
Add a new entry with the specified key and value to the hash table.
If an entry with the same key already exists in the table, the
``freeEntry`` function is invoked with the ``HT_FREE_VALUE`` flag. You
can write your ``freeEntry`` function to free the value of the specified
entry if the old value should be freed. The default ``freeEntry``
function does not free the value of the entry.
:ref:`PL_HashTableAdd` returns ``NULL`` if there is not enough memory to
create a new entry. It doubles the number of buckets if the table is
overloaded.
