Speller Load Function giving SEG Fault at strcpy("cursor->word", word);

Question

while (fscanf(file, "%s", word) != EOF)
{
    // TODO

    node *cursor = malloc(sizeof(node));
    if(cursor == NULL)
    {
        unload();
        return false;
    }
    strcpy("cursor->word",word);
    cursor->next = NULL;
    int i = hash(word);

    if(hashtable[i] == NULL)
    {
        hashtable[i] = cursor;
        sizex++;
    }
    else
    {
        node *temp = hashtable[i];

        while(temp->next)
        {
            temp = temp->next;
        }
        temp->next = cursor;

        sizex++;
    }    

}

Remove the quotation marks around cursor->word. "cursor->word" is a pointer to some read-only location where exactly those characters ({'c', 'u', 'r', ...}), together with a null terminator, are stored. When strcpy tries to copy to that location, you get this nice segfault.

cursor->word instead is the word member of the struct cursor points to.

BTW, better prepend words to the front of the linked list. Order does not matter, and inserting at the front is a constant-time operation, while appending at the end requires you to walk the whole list so far.
