An entry has a key and a value, represented by the following +fields in the ``PLHashEntry`` structure. + +.. code:: + + const void *key; + void *value; + +The key field is a pointer to an opaque key. The value field is a +pointer to an opaque value. If the key of an entry is an integral value +that can fit into a ``void *`` pointer, you can just cast the key itself +to ``void *`` and store it in the key field. Similarly, if the value of +an entry is an integral value that can fit into a ``void *`` pointer, +you can cast the value itself to ``void *`` and store it in the value +field. + +.. warning:: + + **Warning**: There are other fields in the ``PLHashEntry`` structure + besides key and value. These fields are for use by the hash table + library functions and the user should not tamper with them. |
