# 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.
