#include <plhash.h> typedef struct PLHashEntry PLHashEntry;
PLHashEntry is a structure that represents an entry in the hash table. An entry has a key and a value, represented by the following fields in the
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: 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.
