Syntax
|
|
------
|
|
|

|
|
|
#include <plhash.h>
|
|

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.
|
|

|
|
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.
