The size_t type shall be defined as described in <sys/types.h> .
The following shall be declared as functions and may also be defined as macros. Function prototypes shall be provided.
 

int    hcreate(size_t);
void   hdestroy(void);
ENTRY *hsearch(ENTRY, ACTION);
void   insque(void *, void *);
void  *lfind(const void *, const void *, size_t *,
          size_t, int (*)(const void *, const void *));
void  *lsearch(const void *, void *, size_t *,
          size_t, int (*)(const void *, const void *));
void   remque(void *);
void  *tdelete(const void *restrict, void **restrict,
          int(*)(const void *, const void *));
void  *tfind(const void *, void *const *,
          int(*)(const void *, const void *));
void  *tsearch(const void *, void **,
