Sorry....
codice:
#include "lcshash.h" //nome file prototipi
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAXL 256

hashElement_t* getHash(hashTable_t* ht, const char* s){
	int trovato=0;
	hashElement_t* e=ht->table[hashFunction(s,ht)];

	while(trovato==0 && e!=NULL){
		if (strcmp(s,e->key) == 0) trovato=1;
		else e=e->next;
	}

	if (trovato==0)return NULL;
	else return e;
}
