Thread: incompatible type

I'm getting an incompatible type in assignment error for the following code:

((hashNode *)t->data)[hashValue] = (hashNode *)calloc(sizeof(hashNode), 1);


And then the same incompatible types in initialization:

hashNode *previous = ((hashNode *)t->data)[hashValue];


I am implementing a hash bucket with linked list and t is a generic structure and hashNode is a node for the linked list. HashValue is the value of the hashfunction so that I know which array spot to enter the hashvalue. I hope you guys understand what is going on here. Any advice would be great! thanks.

data is declared as an array of what type?

In the second statement you are assigning the hashNode* previous to the value contained in an element of the data array. If data is not an array of hashNode* then this would create a compiler error.
