The array which is to be examined.
The index of the value to obtain. This value must lie within the index space of the array (0 to N-1 inclusive, where N is the count of the array). If the index is outside that range, the behavior is undefined.
Upon return output, will contain the length of the data corresponding to the specified key.
The underlying bytes at the specified index. NULL if the value at the specified index is not a data value.
