Hello, I have a file with format: [name][number][amount] number is taken as a string. and im using it in a strcmp. Problem is that i get a segmentation fault. I know that on most cases when strcmp signs segmentation fault it means that one of the parameters is null or cant find its "end" ('\0'). I checked with gdb and i cant say if this is the problem.Take a look:

Code:

clientsList *lookup_on_Clients(clientsHashTable *hashtable,int hashval,char number[10])
{
 printf("NUMBER:%s\n",number);
 clientsList *list=hashtable[hashval].head;
 for(list; list!=NULL; list=list->next){
   if (strcmp(number,list->number)==0)   //SEGMENTATION!
    return list;

 }
 return NULL;
}


int add ( HashTable* hashtable,char number[10],char* name,int time)
{
     List *new_elem;
    int hashval=hash (hashtable,number);

    new_elem=hashtable[hashval].head;
    if(hashtable[hashval].length>0)
    {                   
          if ((lookup (hashtable,hashval,number))!=NULL) {return 0;}    
    }
    //an den uparxei stoixeio sth lista
    if (!(new_elem=malloc(sizeof(struct clientsList)))){ return -1;}

    //insert values for the new elem
    new_elem->number=strdup(number);    
    new_elem->name=strdup(name);
    new_elem->time=time;

    hashtable[hashval].head=new_elem;
    new_elem->next=NULL;
    hashtable[hashval].length++;

    /* rehash existing entries if necessary */
    if(hashTableSize(hashtable)>= 2*primes[PrimesIndex])    
    {    
         hashtable = expand(hashtable);
         if (hashtable ==NULL){

    return 1;

and the main:

   }

  free(number);
