Problem returning struct pointer

[Prodiga1]

Hi--

I'm having trouble defining a method that is supposed to return a pointer to a struct:

  count_table_t* table_allocate(int size)
  {
          count_table_t *test;
          test=malloc(sizeof(list_node_t)*size);
          return test;
  }

where count_table_t and list_node_t are defined in the header file as:

typedef struct list_node list_node_t;

struct list_node {
  char *key;
  int value;

  list_node_t *next;
};

typedef struct count_table count_table_t;

struct count_table {
  int size;
  //an array of list_node pointers
  list_node_t **list_array;
};

I get a seg fault when running the method. Ideas? Essentially what I'm trying to do is make a count_table object with size: (size*list_node), and then return it.

Try using the same type.

In fact, DON'T use a type at all in the malloc call.
test = malloc ( sizeof(*test) * size );
You can change the type of test, and the malloc will always be right.

Ok.

Does that method do what it is intended to do? Create a count_table_t pointer object and return it?
