c - Passing a pointer to dynamic array

Question

Is it a right way to pass a pointer to dynamic array? Is it going to work? If not, explain why, if it does, explain why as well. Thank you.

struct record
{
    char * community_name;
    double data[10];
    double crimes_per_pop;
};

void allocate_struct_array(struct record *** r);

int main()
{
    /* allocating pointer to an array of pointers */
    struct record ** r;

    /* passing its address to a function */
    allocate_struct_array( &(**r) );
}

/* function gets an address */
void allocate_struct_array(struct record *** r)
{
   ...
}

What I was trying to do is to allocate an array of pointers, where each pointer points to structure record. Function suppose to allocate this array using just pointer to r, which was declared in main. Was playing with this code, but cannot make it to work.

Answer 1

I don't know what you are trying to do, but at least you have a programmatic error.

allocate_struct_array( &(**r) );

needs to be -

allocate_struct_array(&r);
