# PLHashTable (plhashtable-syntax)= ## Syntax ```{code} #include typedef struct PLHashTable PLHashTable; ``` (plhashtable-description)= ## Description The opaque `PLHashTable` structure represents a hash table. Entries in the table have the type `PLHashEntry` and are organized into buckets. The number of buckets in a hash table may be changed by the library functions during the lifetime of the table to optimize speed and space. A new hash table is created by the {ref}`PL_NewHashTable` function, and destroyed by the {ref}`PL_HashTableDestroy` function.
