Expanding a hashtable with linked lists there are some errors and warnings. I wanna make sure that the following code is right (expand method) and find out what happens that raise these warnings/errors
typedef struct
{
int length;
struct List *head;
struct List *tail;
} HashTable;
//resolving collisions using linked lists - chaining
typedef struct
{
char *number;
char *name;
int time;
struct List *next;
}List;
//on the insert method i wanna check hashtable's size,
//if it seems appropriate there is the following code:
//Note: hashtable variable is: Hashtable *
......
hashtable = expand(hashtable,number,name,time); /**WARNING**:assignment makes
pointer from integer without a cast*/
HashTable* expand( HashTable* h ,char number[10],char* name,int time) /**error**:
conflicting types for ‘expand’ previous implicit declaration of ‘expand’ was here*/
{
HashTable* new;
int n;
clientsList *node,*next;
PrimesIndex++;
int new_size= primes[PrimesIndex]; /* double the size,odd length */
if (!(new=malloc((sizeof( List*))*new_size))) return NULL;
for(n=0; n< h->length; ++n) {
for(node=h[n].head; node; node=next) {
add (&new, node->number, node->name,node->time);
next=node->next;////
free(node);
}
}
free(h);
return new;
}
